Anatomy Of Abdominal Muscle
The abdominal muscles form the anterior and lateral abdominal wall and consist of the external abdominal obliques, the internal abdominal obliques, the rectus abdominis and the transversus abdominis . Acting together these muscles form a firm wall that protects the viscera and they help to maintain erect posture. In addition the contraction of these muscles helps in expiration and to increase the intra-abdominal pressure such as in sneezing, coughing, micturating, defecating, lifting and childbirth.
Anatomy Of Back Muscle
The back anatomy includes some of the most massive and functionally important muscles in the human body. Still, many individuals pay far too little attention to them. The back muscles enable you to stand up straight; support and protect your spine; and reach, pull and extend your arms and torso. The superficial back muscles are situated underneath the skin and superficial fascia. They originate from the vertebral column and attach to the bones of the shoulder – the clavicle, scapula and humerus. … The muscles in this group are the trapezius, latissimus dorsi, levator scapulae and the rhomboids
Anatomy Of Lower Back
The lumbar spine (low back) is the third major region of the spine; it is below the cervical spine and thoracic spine. Most people have five bones (vertebrae) in the lumbar spine, although it is not unusual to have six. Each vertebra is stacked on top of the other and between each vertebra is a gel-like cushion called an intervertebral disc. The discs help to absorb pressure, distribute stress, and keep the vertebrae from grinding against each other.
Anatomy Of Biceps Brachii
The biceps is a two-headed muscle and is one of the chief flexors of the forearm. Here is the left side, seen from the front. The biceps, also biceps brachii is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. The biceps is one of three muscles in the anterior compartment of the upper arm, along with the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply. The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid tubercle of the scapula, respectively. From its origin on the glenoid, the long head remains tendinous as it passes through the shoulder joint and through the intertubercular groove of the humerus. Extending from its origin on the coracoid, the tendon of the short head runs adjacent to the tendon of the coracobrachialis as the conjoint tendon. Unlike the other muscles in the anterior compartment of the arm, the biceps muscle crosses two joints, the shoulder joint and the elbow joint.
Anatomy Of Calf Muscle
The gastrocnemius and soleus muscles taper and merge at the base of the calf muscle. Tough connective tissue at the bottom of the calf muscle merges with the Achilles tendon. The Achilles tendon inserts into the heel bone (calcaneus).
Anatomy Of Chest Muscle
The pectoralis major is a large, substantial, fan-shaped muscle. And as you might guess from the word “major,” it makes up the majority of the chest muscle mass. It originates at your clavicle, ribs, and sternum, and inserts into the upper portion of your humerus (upper arm bone from elbow to shoulder.)
Anatomy Of Forearm Muscles
The forearm is the region of the upper limb between the elbow and the wrist. The term forearm is used in anatomy to distinguish it from the arm, a word which is most often used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower “arm” is called the forearm. It is homologous to the region of the leg that lies between the knee and the ankle joints, the crus. The forearm contains two long bones, the radius and the ulna, forming the radioulnar joint. The interosseous membrane connects these bones. Ultimately, the forearm is covered by skin, the anterior surface usually being less hairy than the posterior surface. The forearm contains many muscles, including the flexors and extensors of the digits, a flexor of the elbow (brachioradialis), and pronators and supinators that turn the hand to face down or upwards, respectively. In cross-section the forearm can be divided into two fascial compartments. The posterior compartment contains the extensors of the hands, which are supplied by the radial nerve. The anterior compartment contains the flexors, and is mainly supplied by the median nerve.The flexor muscles are more massive than the extensors, because they work against gravity and act as anti-gravity muscles. The ulnar nerve also runs the length of the forearm. The radial and ulnar arteries and their branches supply the blood to the forearm. These usually run on the anterior face of the radius and ulna down the whole forearm. The main superficial veins of the forearm are the cephalic, median antebrachial and the basilic vein. These veins can be used for cannularisation or venipuncture, although the cubital fossa is a preferred site for getting blood.
Head Push Front And Back
Poor posture with the head too far forward may lead to chronic or recurrent neck pain that can also be accompanied by stiff joints, upper back pain, shoulder blade pain, and headaches. Fortunately, a neck exercise can be able to help neck related issues. Instructions: Step 1.In starting Position place both of your hands on the front side of your head. Step 2.Now gently push forward as you contract the neck muscles but resisting any movement of your head. Start with slow tension and increase slowly. Keep breathing normally as you execute this contraction. Step 3.Hold for the recommended number of seconds. Step4.Now release the tension slowly. Step 5.Rest for the recommended amount of time and repeat with your hands placed on the back side of your head. Alternative Exercises: 1. Isometric Sides Neck Exercise 2. Neck Bridge Prone 3. Neck Sides Stretch 4. Lying Face down Plate Neck Resistance Important Key Points: Perform this exercise With Right Posture and Controlled Movements.
Anatomy Of Neck Muscles
Neck anatomy is a well-engineered structure of bones, nerves, muscles, ligaments and tendons. The cervical spine (neck) is delicate—housing the spinal cord that sends messages from the brain to control all aspects of the body—while also remarkably strong and flexible, allowing movement in all directions. The neck muscles, including the sternocleidomastoid and the trapezius, are responsible for the gross motor movement in the muscular system of the head and neck. They move the head in every direction, pulling the skull and jaw towards the shoulders, spine, and scapula.
Anatomy Of Deltoids Muscle
The deltoid muscle is a rounded, triangular muscle located on the uppermost part of the arm and the top of the shoulder. It is named after the Greek letter delta, which is shaped like an equilateral triangle. The deltoid is attached by tendons to the skeleton at the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). The deltoid is widest at the top of the shoulder and narrows to its apex as it travels down the arm. Contraction of the deltoid muscle results in a wide range of movement of the arm at the shoulder due to its location and the wide separation of its muscle fibers The deltoid has three origins: the lateral end of the clavicle, the acromion of the scapula at the top of the shoulder, and the spine of the scapula. Each origin gives rise to its own band of muscle fibers with the anterior band forming at the clavicle, the lateral fibers forming at the acromion, and the posterior fibers forming at the spine of the scapula. The bands merge together as they approach the insertion point on the deltoid tuberosity of the humerus. The deltoid has three distinct functions that correspond to the three bands of muscle fibers. Contraction of the anterior fibers flexes and medially rotates the arm by pulling the humerus towards the clavicle. Flexion and medial rotation of the arm moves the arm anteriorly, as in reaching forward or throwing a ball underhand. The lateral fibers abduct the arm by pulling the humerus toward the acromion. Abduction of the arm results in the arm moving away from the body, as in reaching out to the side. Contraction of the posterior fibers extends and laterally rotates the arm by pulling the humerus toward the spine of the scapula. Extension and lateral rotation moves the arm posteriorly, as in reaching backwards or winding up to throw a ball underhand.
Anatomy Of Gluteal Muscles
Gluteal muscles. The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.
Anatomy Of Hamstring Muscle
In human anatomy, a hamstring is one of the three posterior thigh muscles in between the hip and the knee (from medial to lateral: semimembranosus, semitendinosus and biceps femoris). In quadrupeds, the hamstring is the single large tendon found behind the knee or comparable area. The three muscles of the posterior thigh (semitendinosus, semimembranosus, biceps femoris long & short head) flex (bend) the knee, while all but the short head of biceps femoris extend (straighten) the hip. The three ‘true’ hamstrings cross both the hip and the knee joint and are therefore involved in knee flexion and hip extension. The short head of the biceps femoris crosses only one joint (knee) and is therefore not involved in hip extension. With its divergent origin and innervation it is sometimes excluded from the ‘hamstring’ characterization.
Anatomy Of Quadriceps Muscle
The Quadriceps are a group of four muscles that sit on the anterior or front aspect of the thigh. They are the Vastus Medialis, Intermedius and Lateralis and finally the Rectus Femoris. The Quadriceps attach to the front of the tibia and originate at the top of the femur.
Anatomy Of Trapezius Muscle
The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilizing the scapula (shoulder blade) and extending the head at the neck. It is a wide, flat, superficial muscle that covers most of the upper back and the posterior of the neck. The Trapezius Muscle is located on the upper back of the human torso and it’s main functions are to move the scapula (shoulder blades), head and neck back and sideways and support the arm
Anatomy Of Triceps Brachii
The triceps brachii (triceps) is a large, three-headed muscle of the upper arm, consisting of the following: long head: originates at the infraglenoid tubercle of the scapula
