What is a somatic efferent neuron?

What is a somatic efferent neuron?

Somatic efferent neurons are motor neurons that conduct impulses from the spinal cord to skeletal muscles. These neurons are multipolar neurons, with cell bodies located in the gray matter of the spinal cord.

What is somatic nervous system in psychology?

The somatic nervous system “maintains communication between the CNS and the outside world”. The somatic nervous system is made up of sensory receptors that carry information to the spinal cord and brain, and motor pathways that allow the brain to control movement.

What is the function of motor efferent neurons?

Efferent neurons, also called motor neurons, are the nerve fibers responsible for carrying signals from the brain to the peripheral nervous system in order to initiate an action. In other words, they are the neurons that tell your body to perform an action, such as removing your hand from a hot pan.

What does somatic efferent innervate?

Somatic efferent fibres innervate voluntary muscles that derive from the myotomes of the embryo. Visceral motor fibres are divided into special visceral efferents, which innervate striped muscles of branchial origin, and general visceral efferents, which innervate involuntary muscles and secreting glands.

What is the difference between somatic and autonomic neurons?

The somatic nervous system has sensory and motor pathways, whereas the autonomic nervous system only has motor pathways. The autonomic nervous system controls internal organs and glands, while the somatic nervous system controls muscles and movement.

What is difference between afferent and efferent?

Explanation: Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.

What are examples of motor neurons?

Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.

What are the types of motor neurons?

There are three broad types of lower motor neurons: somatic motor neurons, special visceral efferent (branchial) motor neurons, and general visceral motor neurons. Somatic motor neurons are in the brainstem and further divide into three categories: alpha, beta, and gamma.
