Final answer:
The option not associated with the autonomic nervous system is B) Skeletal muscle reflex, which is controlled by the somatic nervous system, not the ANS.
Step-by-step explanation:
The function that is not an autonomic nervous system (ANS) function is B) Skeletal muscle reflex. The autonomic nervous system is responsible for regulating involuntary bodily functions such as increasing heart rate, emptying the bladder, and gland secretion. These functions are carried out without conscious effort and are essential for maintaining homeostasis in the body. In contrast, skeletal muscle reflexes are not governed by the ANS, but rather by the somatic nervous system, which controls voluntary movements and reflexes involving skeletal muscles.
