The SAID principle stands for Specific Adaptations to Imposed ___.
Answer: Demands
SAID stands for Specific Adaptations to Imposed Demands, meaning the body adapts specifically to the type and magnitude of stress placed upon it.
Which bone forms the rounded posterior portion of the shoulder joint socket?
Answer: Glenoid fossa of scapula
The glenoid fossa, a shallow cavity on the lateral scapula, forms the socket of the glenohumeral (shoulder) joint.
What is the primary role of the rotator cuff muscles?
Answer: Stabilizing the humeral head in the glenoid fossa
The four rotator cuff muscles (SITS) compress and stabilize the humeral head within the shallow glenoid fossa, preventing dislocation during arm movements.
During eccentric muscle action, the muscle is:
Answer: Lengthening while producing force
Eccentric muscle action occurs when a muscle produces force while being lengthened, such as the biceps during the lowering phase of a bicep curl.
What is the function of the lymphatic system in relation to exercise?
Answer: Returns interstitial fluid to circulation and supports immune function
The lymphatic system collects excess interstitial fluid and returns it to the bloodstream, and it transports immune cells, playing a role in recovery from exercise-induced tissue stress.
What is the term for the movement of a limb away from the midline of the body?
Answer: Abduction
Abduction is the anatomical term for moving a limb away from the body's midline, such as raising the arm laterally in a side lateral raise.
