Kinesiology Chapter 1 Basic Information

Basic information… Kinesiology-study of movement Dynamic Static Related to human movement Musculoskeletal anatomy Neuromuscular physiology Principles of mechanics (biomechanics) Dynamic Kinetics- forces causing movement Kinematics- time, space and mass Static

Concepts to remember… Human body is arranged in a very logical way Visualize it!

Descriptive terminology… Anatomical position Standing Upright position Eyes facing forward Feet parallel and close together Arm at the sides-palms facing forward Fundamental position Palms facing the sides of the body

Terminology cont… Medial Lateral Anterior Posterior Ventral - anterior Dorsal-posterior Distal Proximal

What is what??

Terminology cont … Superior Inferior Cranial/cephalad- head Caudal-tail Cauda equina Superficial/Deep Bilateral/contralateral/ipsilateral Body segments- trunk, thorax, abdomen Upper extremities/lower extremities

Your turn!

Types of motion… Linear motion- translatory motion Rectilinear motion Curvilinear motion- curved path Angular motion- rotatory motion All parts move through the same angle, direction and time They do not move the same distance Combination E.g. wheelchair

Motion???

Joint movements Occurs around joint axis and through planes Osteokinematics- bones moving around a joint axis (synovial joints) e.g. ABDUCTION Arthrokinematics- relationship of joint surface movement **e.g. what happens inside the articulation p6

Osteokinematics… Flexion- two segments closer, increased angle? anterior surfaces, mostly Knee vs. neck Extension- two segments moving away, return to anatomical position. *Hyperextension- continuation of extension Beyond anatomical position e.g. knee-female vs. males

Osteokinematics cont.. Abduction- away from midline Adduction- towards midline Exceptions fingers (3rd ) and toes (2nd) Horizontal abduction (90 degrees/shoulder flexion) Horizontal adduction (90 degrees/ shoulder flexion) Radial deviation Ulnar deviation

…

Osteokinematics cont… Lateral bending – trunk Lateral flexion not used in this book

Osteokinematics cont… Inversion –foot inward Eversion- foot outward Protraction- linear movement parallel to ground/away from midline Retraction-linear motion towards midline

Osteokinematics cont… Circumduction- cone-shaped pattern 4 motions Flexion Abduction Extension Adduction Rotation Medial rotation/internal rotation Lateral rotation/ external rotation Supination- palm up Pronation-palm down

B. The ribs are___________ to the scapula. C. The__________ end of the humerus is at the elbow joint. D. The brachialis muscle lies underneath the biceps; therefore, it is_______ to the biceps. E. The head is___________ to the chest. F. The end of the tibia is ___________at the knee joint.
