Question

human reproductive system test unit test
which system is disrupted when a person hits their head while diving, causing paralysis from the waist down?
(1 point)
○ cardiovascular system
○ circulatory system
○ nervous system
○ endocrine system

Explanation:

Paralysis involves loss of motor or sensory function, which is controlled by the nervous system (brain, spinal cord, nerves). Hitting the head can damage the nervous system (e.g., spinal cord injury), disrupting signals to the lower body. The cardiovascular/circulatory systems involve blood flow, and the endocrine system involves hormones—neither directly cause paralysis from head trauma.

Answer:

C. nervous system
