Male erection is an example of ______. No thought or emotion is required for it to occur, but conscious control can influence it.
A) peripheral nerves
B) sensory nerves
C) a spinal reflex
D) A sexual reflex
I chose choice A because the book states the following " sensory nerves carry massages from special receptors in the skin, muscles and other internal and external sense organs to the spinal cord , which sends them along the brain. These nerves put us in touch with both the outside world and activities of our own body."
a sexual reflex
A spinal reflex , read the cental cervous system on your book.
The correct answer is C) a spinal reflex.
To explain why, let's break it down:
- A peripheral nerve refers to a nerve that is located outside the central nervous system, such as in the limbs or organs. While peripheral nerves may play a role in transmitting signals related to male erection, they are not the main factor.
- Sensory nerves are responsible for carrying information from sensory receptors to the spinal cord and brain. While sensory nerves are involved in transmitting tactile sensations and other information related to sexual stimulation, they do not directly cause erections.
- A spinal reflex is an automatic response that occurs without conscious control, through the spinal cord. In the case of a male erection, a sexual reflex is at play. This reflex is triggered by physical stimulation of certain areas, such as the , which activates sensory receptors that send signals to the spinal cord. The spinal cord then sends signals back to the , leading to an erection.
So, while peripheral and sensory nerves are involved in the process, it is ultimately the spinal reflex that governs the occurrence of a male erection. Conscious control can also influence erections, but the initial reflex is independent of conscious thought or emotion.
