The afferent or sensory division transmits impulses from peripheral organs to the CNS. The efferent or motor division transmits impulses from the CNS out to the peripheral organs to cause an effect or action.
What is afferent and efferent nervous system?
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 is the afferent division of the nervous system called?
The sensory (afferent) division carries sensory signals by way of afferent nerve fibers from receptors in the central nervous system (CNS). It can be further subdivided into somatic and visceral divisions. The somatic sensory division carries signals from receptors in the skin, muscles, bones and joints.
What are the 2 efferent divisions of the peripheral nervous system?
The efferent division is further divided into the somatic efferent division, which consists of neurons that control skeletal muscles, and the autonomic efferent division, which consists of the neurons that control all other organs (collectively termed viscera).What are the 2 main divisions of the nervous system?
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
What are the divisions of the nervous system and their functions?
The anatomical divisions are the central and peripheral nervous systems. The CNS is the brain and spinal cord. The PNS is everything else and includes afferent and efferent branches with further subdivisions for somatic, visceral and autonomic function.
What are the three divisions of the nervous system?

What are the basic divisions of the peripheral nervous system quizlet?
- The peripheral nervous system. has two major divisions: the somatic nervous system and the autonomic nervous system.
- somatic nervous system. …
- autonomic nervous system.
What are the two main divisions of the nervous system quizlet?
The structures of the nervous system are described in terms of 2 principal divisions-the central nervous system (CNS) and the peripheral nervous system (PNS).
What are the 6 divisions of the nervous system?The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
Article first time published onWhat are the four divisions of the nervous system?
- Cranial nervous system.
- Peripheral nervous system.
- Autonomic nervous system.
- Central nervous system.
Is the name of the nervous system division?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
What are the 4 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.
What are the three divisions of the human nervous system class 10?
- The central nervous system(brain and spinal cord)
- The peripheral nervous system.
- The autonomic nervous system.
What are the 3 major functions of the nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
