What type of innervation does the breast have?
a. Both sensory and sympathetic
b. Both sensory and parasympa thetic
c. Both parasympathetic and sympathetic
d. Only sympathetic
e. Only parasympathetic
The correct answer is: a. Both sensory and sympathetic
The breast receives both sensory and sympathetic innervation:
– Sensory innervation:
– Provides sensation to the breast, including touch, pressure, pain, and temperature
– Afferent nerve fibers transmit signals from the breast to the spinal cord and brain
– Sympathetic innervation:
– Regulates blood flow and sweat glands in the breast
– Sympathetic nerve fibers release neurotransmitters like norepinephrine, which cause blood vessels to constrict and reduce blood flow
