	~~'''Neurite''' is a term used in neuroscience to describe a projection~~ from the body of a neuron, specifically a [[neuron]] or nerve cell. Neurites are essential components of neurons, as they are responsible for receiving and transmitting signals from and to other neurons. There are two types of neurites: [[axon]]s and [[dendrite]]s.		{{Short description\|Outgrowths from the cell body of a neuron}}

	== ~~Structure~~ ==		==Neurite==
			A '''neurite''' refers to any projection from the cell body of a neuron. This term encompasses both [[axon]]s and [[dendrite]]s, which are the two types of extensions that neurons use to communicate with each other and with other types of cells. Neurites are crucial for the proper functioning of the [[nervous system]], as they facilitate the transmission of electrical and chemical signals.

	Neurites are ~~made up~~ of ~~a substance called [[neuroplasm]]~~, which ~~is enclosed by a [[cell membrane]]. The neuroplasm contains [[organelle]]s and a [[cytoskeleton]], which helps to maintain~~ the ~~shape~~ of the ~~neurite~~ and ~~transport substances along its length~~.		==Structure and Function==
			Neurites are essential components of neurons, which are the primary cells of the nervous system. Each neuron typically has one axon and multiple dendrites. The axon is responsible for transmitting signals away from the cell body, while dendrites receive signals from other neurons.

	== ~~Function~~ ==		===Axons===
			Axons are long, slender projections that can extend over great distances within the body. They are specialized for the rapid transmission of electrical impulses, known as action potentials. The axon terminal, or synaptic bouton, is the site where the axon makes contact with other neurons or effector cells, such as muscle cells.

	~~The primary function of neurites is to transmit signals~~ from ~~one neuron to another~~. ~~This is achieved through the process of~~ [[~~synaptic transmission~~]], ~~where an electrical signal in one neuron triggers~~ the ~~release~~ of ~~[[neurotransmitter]]s into~~ a ~~small gap called~~ the ~~[[synapse]]. These neurotransmitters then bind~~ to ~~receptors on~~ the ~~neurite of a neighboring neuron, triggering an electrical signal in that~~ neuron.		===Dendrites===
			Dendrites are shorter, branched projections that receive input from other neurons. They contain numerous [[synapse]]s, which are the points of communication between neurons. Dendrites play a critical role in integrating synaptic inputs and determining the extent to which the neuron will respond to incoming signals.

	== ~~Growth and~~ Development ==		==Development==
			Neurite outgrowth is a key process during the development of the nervous system. It involves the extension of axons and dendrites from the cell body, guided by a variety of molecular cues. This process is essential for the formation of functional neural circuits.

	~~The growth and development of neurites is a complex process that is regulated by a variety of factors, including~~ [[~~gene expression]], [[protein synthesis]], and the local environment~~. ~~This process, known as [[neuritogenesis~~]]~~, is crucial for the formation of the complex networks of neurons that make up the [[nervous system]].~~		[[File:Neurite_growth_in_a_microfluidic_device.webm\|Neurite growth in a microfluidic device\|thumb\|right]]

	== ~~Clinical Significance~~ ==		===Neurite Outgrowth===
			Neurite outgrowth is influenced by both intrinsic factors, such as the expression of specific genes, and extrinsic factors, such as the presence of growth factors and extracellular matrix components. The growth cone, a dynamic structure at the tip of a growing neurite, plays a crucial role in sensing the environment and directing neurite extension.

	~~Abnormalities~~ in ~~neurite growth and development~~ can ~~lead~~ to ~~a variety~~ of ~~neurological disorders, including [[neurodegenerative disease]]s like [[Alzheimer's disease]] and [[Parkinson's disease]], and psychiatric disorders like [[schizophrenia]] and [[autism]]~~.		===Regeneration===
			In the adult nervous system, the ability of neurites to regenerate after injury is limited, particularly in the central nervous system. However, in the peripheral nervous system, axons can regenerate to some extent, allowing for the recovery of function after injury.

	== ~~See Also~~ ==		==Clinical Significance==
			Neurite outgrowth and regeneration are important areas of research in the context of [[neurodegenerative disease]]s and [[spinal cord injury]]. Understanding the mechanisms that regulate neurite growth could lead to new therapeutic strategies for promoting neural repair and recovery.

'''Neurite''' is a term used in neuroscience to describe a projection from the body of a neuron, specifically a [[neuron]] or nerve cell. Neurites are essential components of neurons, as they are responsible for receiving and transmitting signals from and to other neurons. There are two types of neurites: [[axon]]s and [[dendrite]]s.

== Structure ==

Neurites are made up of a substance called [[neuroplasm]], which is enclosed by a [[cell membrane]]. The neuroplasm contains [[organelle]]s and a [[cytoskeleton]], which helps to maintain the shape of the neurite and transport substances along its length.

== Function ==

The primary function of neurites is to transmit signals from one neuron to another. This is achieved through the process of [[synaptic transmission]], where an electrical signal in one neuron triggers the release of [[neurotransmitter]]s into a small gap called the [[synapse]]. These neurotransmitters then bind to receptors on the neurite of a neighboring neuron, triggering an electrical signal in that neuron.

== Growth and Development ==

The growth and development of neurites is a complex process that is regulated by a variety of factors, including [[gene expression]], [[protein synthesis]], and the local environment. This process, known as [[neuritogenesis]], is crucial for the formation of the complex networks of neurons that make up the [[nervous system]].

== Clinical Significance ==

Abnormalities in neurite growth and development can lead to a variety of neurological disorders, including [[neurodegenerative disease]]s like [[Alzheimer's disease]] and [[Parkinson's disease]], and psychiatric disorders like [[schizophrenia]] and [[autism]].
