What else can I help you with?
In contrast to the somatic nervous system the automonic nervous system?
Has two efferent neurons.
Which nervous system contains all the sensory neurons and all the voluntary motor neurons?
A somatic system
What system consist of sensory and motor neurons associated with voluntary actions?
The somatic nervous system consists of sensory and motor neurons that are associated with voluntary actions. Sensory neurons transmit sensory information from the body to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles to initiate movement. This system allows for conscious control over skeletal muscle movement.
What is Skeletal muscles controlled by?
Skeletal muscles are controlled by motor neurons in the somatic branch of the peripheral nervous system, which is controlled by the central nervous system.
What is somatic nervous system?
The somatic nervous system transmits sensory messages to the central nervous system. The somatic nervous system is a sub group of the peripheral nervous system, it mainly controls voluntary muscles and sense organs.
Where are somatic neurons located?
in the CNS
In contrast to the somatic nervous system the autonomic nervous system?
The autonomic nervous system regulates involuntary functions like heart rate and digestion, while the somatic nervous system controls voluntary movements. The autonomic nervous system has two branches: the sympathetic and parasympathetic nervous systems, which have opposing effects on the body. The somatic nervous system mainly controls skeletal muscle movement through motor neurons.
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
Is acetylcholine the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons?
Yes, acetylcholine is the substance released by the axon terminals of both somatic motor neurons and postganglionic parasympathetic neurons. In the somatic nervous system, acetylcholine is released at the neuromuscular junction, while in the parasympathetic nervous system, it is released at synapses with target organs.
What are two parts of the peripheral nervous system?
The two parts of the peripheral nervous system are the somatic nervous system, responsible for voluntary movements and sensory input, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.
What neurons normally have the shortest axons?
Interneurons typically have the shortest axons in the nervous system. They are responsible for processing information and signaling between sensory and motor neurons within the central nervous system.
What PNS system controls skeletal muscles?
The somatic nervous system controls skeletal muscles. It is responsible for voluntary movements and receives input from sensory neurons to help coordinate muscle contractions.
