2023年10月30日 · In summary therefore, cranial nerve nuclei are either motor (efferent) or sensory (afferent), and both category can be somatic or visceral. An overview of the brainstem may be useful as this region houses the nuclei that give rise to …

house the cell bodies of somatic motor neurons, which innervate skeletal muscle. are found in the T1-L2 parts of the spinal cord only. Contain cell bodies of autonomic motor neurons, which innervate cardiac and smooth muscle and glands. contain axons of sensory neurons and cell bodies of interneurons.

The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1]

2022年11月7日 · The somatic nervous system is a component of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. It is responsible for all the functions we know and can consciously influence, including moving our arms, legs, and other body parts.

The goal of this Appendix is to review the functional organization of the somatic sensory system, from the activation of the peripheral receptors to the discharge of neurons in the somatosensory cortex.

2022年12月13日 · The somatic nervous system is part of the peripheral nervous system and plays a role in voluntary movements and sensory processing. The somatic nervous system carries motor and sensory signals to and from the central nervous system (CNS).

2024年7月9日 · The cranial nerve nuclei are a series of bilateral grey matter motor and sensory nuclei located in the midbrain, pons and medulla that are the collections of afferent and efferent cell bodies for many of the cranial nerves.. Some nuclei are small and contribute to a single cranial nerve, such as some of the motor nuclei. Other nuclei, however, are long and span …

2024年11月17日 · Anatomy and Physiology I (OpenStax) Chapter 14: Somatic Sensory and Somatic Motor Systems I. Introduction: The somatic nervous system is responsible for our conscious perception of the environment and for our voluntary responses to that perception by means of skeletal muscles.

Primarily the trigeminal nuclei, receiving general somatic sensations from the face, including pain, temperature, touch, pressure, vibration, and proprioception. Receive sensory information regarding hearing and balance. Receive and process taste information from the tongue and oropharyngeal region.
