You have a nerve that carry the impulses from inner ear to brain. It is sensory nerve. It is the 8th nerve. It is called as vestibulocochlear nerve.
Its called gating in that the nerve impulses from the foot overload the pain stimpuli impulses from elsewhere preventing or reducing their access to the spinal cord and thence to the brain where pain is perceived
True
The membrane surrounding an entire nerve is called the epineurium. It provides protection and support to the nerve fibers within and helps maintain the structural integrity of the nerve as a whole. The epineurium also assists in the transmission of nerve impulses along the nerve.
Large diameter nerve fibers have less resistance to the flow of electrical signals compared to small diameter fibers. This allows for faster conduction of impulses along the nerve fibers. Consequently, large diameter fibers are responsible for quick reflex responses in the body.
Neuron is another name for a nerve cell.
The Trochlear Nerve
Brain send the message via nerve impulses involving neurons which use the neuro-transmitter AcetylcholineAcetylcholine- a neurotransmitter released at the neuromuscular junction triggers a muscle action potential, which leads to muscle contraction
