Chapter 11 Neural Function
1. More complex patterns of movements, such as throwing a ball or picking up a
fork, are controlled by the cortex in the frontal lobe.
A) premotor
B) primary motor
C) reflexive
D) supplementary
2. Disorders of the pyramidal tracts, such as a stroke, are characterized by:
A) paralysis.
B) hypotonia.
C) muscle rigidity.
D) involuntary movements.
3. Myasthenia gravis is characterized by muscle weakness caused by antibody-
mediated destruction of:
A) periorbital muscles.
B) thymus gland cells.
C) skeletal muscle fibers.
D) acetylcholine receptors.
4. A patient has wrist inflammation causing compression of the median nerve
in the carpal tunnel. Manifestations of this syndrome include:
A) little finger numbness.
B) forearm paresthesia.
C) loss of tendon reflexes.
D) precision grip weakness.
5. The cardinal symptoms of Parkinson disease include:
A) hypotonia.
, B) bradykinesia.
C) paresthesia.
