Neurons in which dendritic and axonal processes are continuous and the soma lies off to one side are called?
Bipolar neurons have only one axon and one dendrite with the soma between them. There are probably very few, if any, neurons that contain only a single axon and dendrite. However, the concept is useful because some neurons behave as if they only had a single axon and dendrite. These neurons, called bipolar neurons because their cell body sits in between the axon and dendrite (giving the neuron two "poles"), are abundant in the nervous system. One very important type of bipolar neuron occurs in the retina, and is responsible for how we process light at an early level.

Are ribosomes associated with axon?
Ribosomes are primarily involved in protein synthesis and are typically found in the cytoplasm of cells, including neurons. While they are not directly associated with the axon itself, ribosomes can be found in the cell body and dendrites of neurons, where they produce proteins necessary for axonal function and maintenance. In some cases, ribosomes may also be present in the axonal cytoplasm, contributing to local protein synthesis critical for axonal growth and repair.
What is axonal transmission?
Axonal transmission is the process by which electrical signals are transmitted along the axon of a neuron. It involves the propagation of action potentials, or electrical impulses, from the cell body of the neuron to the axon terminals where neurotransmitters are released. This process is essential for communication between neurons in the nervous system.
What are groups of neurons send connections from the cortex deep into the brain?
The corticothalamic neurons are groups of neurons that send connections from the cortex deep into the brain to the thalamus. They play a crucial role in regulating the flow of information between different brain regions and are involved in sensory processing, attention, and consciousness.
What do we call the connections between the nerve cells?
An axo-axonal synapse is what a connection specifically between one axon and another axon is called. The general term for a connection between neurons is SYNAPSE, and typically is between an axon and a dendrite.
What is active axon loss?
Active axon loss refers to the process in which the axons of neurons degenerate due to specific pathological mechanisms, such as inflammation or direct injury. This type of degeneration involves the breakdown of axonal structure and can contribute to neurological disorders and impairments in nerve function. Active axon loss is different from passive axon degeneration, which occurs as a result of more general cell death processes.
Why the flow of signal in synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse?
i dont no
What two physiogolical characteristics highly developed in neorons?
Neurons have highly developed cell membranes that allow for efficient communication through electrical and chemical signals. They also possess extensive dendritic arborizations and axonal projections, enabling long-distance connectivity and integration of information within the nervous system.
What does axonal mean?
Axonal refers to something related to an axon, which is a long, slender projection of a nerve cell that conducts electrical impulses away from the cell body. Axonal processes are crucial for transmitting information within the nervous system.
Are ribosomes associated with axon?
Ribosomes are primarily involved in protein synthesis and are typically found in the cytoplasm of cells, including neurons. While they are not directly associated with the axon itself, ribosomes can be found in the cell body and dendrites of neurons, where they produce proteins necessary for axonal function and maintenance.

What do The anterior horns of the spinal cord contain?
do you mean dorsal or ventral horn?ventral (closest to belly) contain fibres going out to the body, so ones terminating in tissuesdorsal (closest to back) contains fibres travelling from the body towards the CNS, carrying sensory informationgrey matter is made of neurons (their cell bodies) white matter consists of axons (their processes)white matter is white due to the fatty protein rich myelin which coats the processes but not the cell body
Which area would contain an abundance of vesicles containing neurotransmitter?
Synaptic terminals at the axon terminals of neurons would contain an abundance of vesicles containing neurotransmitters. These vesicles release neurotransmitters into the synaptic cleft to facilitate communication between neurons.

What is axonal recruitment?
Axonal recruitment refers to the process by which motor neurons control muscle contraction by selectively activating more or fewer muscle fibers. As the strength of a muscle contraction increases, more motor units are activated and more muscle fibers are recruited, leading to a more forceful contraction. Axonal recruitment plays a crucial role in the fine control of movements and is essential for activities that require varying degrees of force, such as lifting objects of different weights or controlling the speed and force of movements during physical activities.
