Afferent nerve fiber

Index Afferent nerve fiber

Afferent nerve fibers refer to axonal projections that arrive at a particular region; as opposed to efferent projections that exit the region. [1]

Autonomic nervous system

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs.

Axon

An axon (from Greek ἄξων áxōn, axis) or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses known as action potentials, away from the nerve cell body.

Central nervous system

The central nervous system (CNS) is the part of the nervous system consisting of the brain and spinal cord.

Dendrite

Dendrites (from Greek δένδρον déndron, "tree"), also dendrons, are branched protoplasmic extensions of a nerve cell that propagate the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

Dorsal root ganglion

A dorsal root ganglion (or spinal ganglion) (also known as a posterior root ganglion), is a cluster of neurons (a ganglion) in a dorsal root of a spinal nerve.

Dorsal root of spinal nerve

The dorsal root of spinal nerve (or posterior root of spinal nerve) is one of two "roots" which emerge from the spinal cord.

Efferent nerve fiber

In the peripheral nervous system, an efferent nerve fiber is the axon of a motor neuron.

Extrafusal muscle fiber

Extrafusal muscle fibers are the skeletal standard muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby allowing for skeletal movement.

Ganglion

A ganglion is a nerve cell cluster or a group of nerve cell bodies located in the autonomic nervous system and sensory system.

General somatic afferent fibers

The general somatic afferent fibers (GSA, or somatic sensory fibers) afferent fibers arise from cells in the spinal ganglia and are found in all the spinal nerves, except occasionally the first cervical, and conduct impulses of pain, touch and temperature from the surface of the body through the dorsal roots to the spinal cord and impulses of muscle sense, tendon sense and joint sense from the deeper structures.

General visceral afferent fibers

The general visceral afferent fibers (GVA) conduct sensory impulses (usually pain or reflex sensations) from the internal organs, glands, and blood vessels to the central nervous system.

Golgi tendon organ

The Golgi tendon organ (GTO) (also called Golgi organ, tendon organ, neurotendinous organ or neurotendinous spindle) is a proprioceptive sensory receptor organ that senses changes in muscle tension.

Interneuron

An interneuron (also called internuncial neuron, relay neuron, association neuron, connector neuron, intermediate neuron or local circuit neuron) is a broad class of neurons found in the human body.

Intrafusal muscle fiber

Intrafusal muscle fibers are skeletal muscle fibers that serve as specialized sensory organs (proprioceptors) that detect the amount and rate of change in length of a muscle.

Motor neuron

A motor neuron (or motoneuron) is a neuron whose cell body is located in the motor cortex, brainstem or the spinal cord, and whose axon (fiber) projects to the spinal cord or outside of the spinal cord to directly or indirectly control effector organs, mainly muscles and glands.
