Which neuron layers of an axon form the optic nerve?
There are three layers of neurons in the retina. The axons of GANGLION CELLS form the optic nerves.
Once a sympathetic preganglionic axon reaches a trunk ganglion what can it do?
it can 1. synapse with a ganglionic neuron in the same trunk ganglion, 2. ascend or descend the sympathetic trunk to synapse in another trunk ganglion or 3. pass through the trunk ganglion and emerge from the sympathetic trunk without synapsing The answer: Synapse with a parasympathetic neuron in the same trunk ganglion
What are highly branched parts of the nerve cells?
axon
What are the 3 things that sympathetic preganglionic axon reaches a trunk ganglion?
Sympathetic preganglionic axons reach a trunk ganglion through three key pathways: (1) they may synapse directly with postganglionic neurons in the ganglion, (2) they can ascend or descend within the sympathetic trunk to synapse at a different ganglion, or (3) they may pass through the ganglion without synapsing and continue to target organs via splanchnic nerves. These pathways enable the sympathetic nervous system to coordinate responses throughout the body effectively.
What structure contains the cell body (soma) of a sensory nerve receiving sensory information from the skin?
A typical neuron possesses a cell body called soma, dendrites and axon. The sensory nerve cells receiving information from the skin are pseudounipolar cells having two axon. One axon extends centrally towards the spinal cord and the other axon extends towards the skin. The soma of these nerve cells having neurofilaments of specialized proteins receive sensory information through electric and chemical signals called neurotransmitters.A typical neuron possesses a cell body called soma, dendrites and axon.

What are axon tips?
Axon tips are the small structures located at the end of an axon, which are responsible for transmitting electrical impulses to other neurons or cells. They contain synaptic vesicles that store neurotransmitters, which are released into the synaptic cleft to communicate with neighboring cells. Axon tips are essential for the propagation of signals in the nervous system.
Which cell will help an axon regrow from the soma?
Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system play a role in promoting axon regrowth following nerve injury. These cells provide structural support and release growth factors that facilitate axon regeneration.
What are the parts of the nerves cells?
The head, axon and the nerve endings
What is the side branch of the axon?
The side branches of the axon are called axon collaterals. They are smaller branches that extend from the main axon and allow for communication with multiple target cells simultaneously. Axon collaterals play a key role in neural communication and signal transmission.
Where is the point on axon that a signal can be transmitted?
Signals are transmitted along the axon at the axon terminals or synaptic boutons. These structures are located at the ends of axon branches and contain neurotransmitter-filled vesicles that are released into the synapse to communicate with neighboring cells.
What is the pathway of action potential through the conducting system?
From dendrites to cell body to axon to axon terminals, in case of nerve cells.
Synaptic vesicles are found in what?
Synaptic vesicles are found in the axon terminals of nerve cells.
