Module 5) NURS 120 Module 5 Chapter 8: Latest
Updated A+ Guide Solution
/Abduction - Answer-moving away from the midline of the body; opposite motion of
adduction
/.acetylcholine (ACh) - Answer-chemical neurotransmitter
/.Actin - Answer-contractile protein found in the thin myofilaments of skeletal muscle
/.Adduction - Answer-moving toward the midline of the body (or region); opposite of
abduction
/.adductor muscle - Answer-any of several muscles that adduct a joint, moving a body
part in from the side (lateral) and thus toward the midline (median or midsagittal plane)
of the body or of the body region; for example, the pectoralis major and latissimus dorsi
muscles contract together to pull the arm toward the trunk, thus adducting the shoulder
joint
/.aerobic training - Answer-continuous vigorous exercise requiring the body to increase
its consumption of oxygen and develop the muscles' ability to sustain activity over a
long period
/.all or none - Answer-describing a process that occurs at maximum or not at all once it
begins
/.Antagonist - Answer-any agent that has the opposite effect of the agent to which it is
compared; for example, a hormone antagonist opposes the effect of the compared
hormone
/.biceps brachii - Answer-the primary flexor of the forearm
/.biomechanical engineering - Answer-discipline of engineering that applies principles of
mechanical engineering to biological systems, as in biomedical engineering
/.Bursa (pl., bursae) - Answer-small, cushionlike sac found alongside joints, cushioning
moving bones
/.cardiac muscle - Answer-the type of muscle tissue that makes up most of the heart
wall
/.carpal tunnel syndrome - Answer-muscle weakness, pain, and tingling in the radial
side (thumb side) of the wrist, hand, and fingers—sometimes radiating to the forearm
, and shoulder; caused by compression of the median nerve within the carpal tunnel (a
passage along the ventral concavity of the wrist)
/.Circumduction - Answer-the process of moving the distal end of a body part in a
circular path
/.concentric contraction - Answer-type of isotonic muscle contraction in which a muscle's
length decreases
/.Deltoid - Answer-triangular; for example, the deltoid muscle
/.Diaphragm - Answer-membrane or partition that separates one thing from another; the
flat muscular sheet that separates the thorax and abdomen and is a major muscle of
respiration
/.disuse atrophy - Answer-when prolonged inactivity results in the muscles shrinking in
size
/.Dorsiflexion - Answer-angular movement when the top of the foot is elevated (brought
toward the front of the leg) with the toes pointing upward
/.eccentric contraction - Answer-type of isotonic muscle contraction in which a muscle's
length increases under a load
/.endurance training - Answer-continuous vigorous exercise requiring the body to
increase its consumption of oxygen and developing the muscles' ability to sustain
activity over a prolonged period
/.Ergonomics - Answer-applied study of workers and their work environment
/.Eversion - Answer-foot movement that turns the ankle so that the sole faces out to the
side
/.Extension - Answer-increasing the angle between two bones at a joint
/.external oblique - Answer-the outermost layer of the anterolateral abdominal wall
/.Fatigue - Answer-loss of muscle power; weakness
/.fibularis group - Answer-leg muscles that plantar flex and evert the foot; formerly called
peroneous group
/.Flexion - Answer-act of bending; decreasing the angle between two bones at the joint
/.frontal muscle - Answer-one of the muscles of facial expression; it moves the
eyebrows and furrows the skin of the forehead
