What is a somatic function?
The somatic nervous system is part of the peripheral nervous system. Major functions of the somatic nervous system include voluntary movement of the muscles and organs and reflex movements. In the process of voluntary movement, sensory neurons carry impulses to the brain and the spinal cord.
What are the functions of the somatic and autonomic nervous system?
The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions.
What is somatic functioning?
Functions of the Somatic Nervous System. The somatic system is the part of the peripheral nervous system that is responsible for carrying motor and sensory information both to and from the central nervous system (CNS). This system is made up of nerves that connect to the skin, sensory organs, and all skeletal muscles.
What does the somatic nervous system stimulate?
The function of somatic nervous system is to control and manage the movements of the skeletal muscles voluntarily. There are efferent nerves located in somatic nervous system to stimulate muscle contractions.
What does somatic reflexes activate?
Somatic reflexes always involve the CNS, even in a monosynaptic reflex in which the sensory neuron directly activates the motor neuron. That synapse is in the spinal cord or brain stem, so it has to involve the CNS. However, in the autonomic system there is the possibility that the CNS is not involved.
What do functions do somatic receptors have?
Somatic receptors are modified nerve cell endings located in the skeletal muscles, joints, and sense organs (eyes, ears, mouth, and nose). When stimulated, the somatic receptors generate electrochemical impulses or action potentials in the axons of somatic sensory neurons (afferent neurons).
