Which neurotransmitter is responsible for the voluntary movement of muscles in your arm?

Which neurotransmitter is responsible for the voluntary movement of muscles in your arm?

acetylcholine

What would be the effect on the EPSP if the concentration of the enzyme responsible for degrading the excitatory neurotransmitter increased dramatically in the synapse see Section 43.3 page?

What would be the effect on the EPSP if the concentration of the enzyme responsible for degrading the excitatory neurotransmitter increased dramatically in the synapse? It would decrease the magnitude of the EPSP.

What is the space between the presynaptic and postsynaptic membranes?

There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft.

Where are voltage gated channels most abundant?

dendrites

Which neurotransmitter S is are the body’s natural pain killer?

In review, beta-endorphins are proteins that are primarily synthesized by the pituitary gland in response to physiologic stressors such as pain. They function through various mechanisms in both the central and peripheral nervous system to relieve pain when bound to their mu-opioid receptors.

Which is the largest Neuroglia cell?

Astrocytes

Are there more sensory or motor neurons?

Motor nerves transmit the signals from the CNS to the sensory organs and thus, help in initiating actions. These neurons are located at the ventral root ganglion of the spinal cord….Sensory Vs Motor Neurons.

Bases	Sensory Neurons	Motor Neurons
Quantity	10 million sensory neurons	Half a million motor neurons

How does the brain process sensory information?

Information processing starts with input from the sensory organs, which transform physical stimuli such as touch, heat, sound waves, or photons of light into electrochemical signals. The sensory information is repeatedly transformed by the algorithms of the brain in both bottom-up and top-down processing.
