Description

Movement analysis assignment: In this assignment you will identify and describe anatomical structures and functions of the human body.  And, analyze how these structures work during specific tasks in a common area of occupation. Instructions: You will select an activity of your choice that involves the Upper Extremity ( pick up a cup from the counter).  Then, you will take 3 photos (segments) that you will analyze and describe by using proper anatomical terminology.  You will describe the skeletal system, joint, muscles involved, planes/axis rotation. 4-5 pages

ANATOMICAL STRUCTURES AND FUNCTIONS OF HUMAN BODY

2

The human body is organized into various structures. One of them being support and movement
involving intergumentary system, bone tissue, skeletal system, joints, muscular system and
muscular tissue. The intergumentary system which’s the skin has smooth arrector muscles which
contract erecting hairs thus compressing sebaceous glands and help in secretion of oily product
on skin. Other skin structures are nails, mammary glands and enamel of teeth. The subcutaneous
tissue provides body’s fat storage. Skin synthesizes and stores vitamin D .Bones provide support,
protection, movement, storage of the electrolytes and development of blood cells. Long bones
are tubular e.g. humerus of arms. Short bones are cuboidal and found only in ankles (tarsus) and
wrist (carpus).Flat bones serve in protective functions like bones of cranium protect the brain.
Irregular bones have variable shapes e.g. bones of face. Sesamoid bones like the knee or patella
cap are found where tendons cross ends of long bones in limbs which help in protecting the
tendons from excessive wear (Dalley, 2009).
Synovial joints bones are lined by synovial membrane e.g. joint cavity of a knee. Bones
of fibrous tissue include sutures of cranium. Most common is the freely movable synovial joints.
They are classified into plane joint, hinge joint, saddle joint, condyloid joints, ball and socket
joints and pivot joints. Plane joint allows sliding or gliding movements in plane of the articular
surfaces. They are small and numerous e.g. acromioclavicular joint between acromion of scapula
and clavicle. Hinge joint allows flexion and extension. Joint capsule is thin, anterior and
posterior where movement takes place. .g. elbow joint. Saddle joint allow movements that occur
around axes at right angles to each other. The opposite articular surfaces are shaped like a saddle
e.g. arpo-metacarpal joint at the base of first digit. Condyloid joints allow flexion, extension,
abduction and adduction. Movement in one plane is greater than in other e.g.
metacarpophalangeal joints of knuckle joints. Ball and socket joints permit movement in

example a hip joint. Pivot joint allows rotation around central axis e.g. median joint where atl...
