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
