What is the function of sensory afferent neurons?
Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.
What does the motor neuron do?
Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.
What is a interneuron psychology?
n. any neuron that is neither sensory nor motor but connects other neurons within the central nervous system.
What causes motor neurone disease?
It’s caused by a problem with cells in the brain and nerves called motor neurones. These cells gradually stop working over time. It’s not known why this happens. Having a close relative with motor neurone disease, or a related condition called frontotemporal dementia, can sometimes mean you’re more likely to get it.
What is a dendrite vs axon?
1. Dendrites receive electrochemical impulses from other neurons, and carry them inwards and towards the soma, while axons carry the impulses away from the soma. 2. Dendrites are short and heavily branched in appearance, while axons are much longer.
What is a axon?
Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.
What is different and efferent?
These connect sense organs with the central nervous system. b) Motor neurons: They are also known as an effector or efferent neurons. These connect the central nervous system to the effectors….Distinguish between afferent and efferent neurons.
|They carry sensory impulses towards the CNS.
|They carry motor impulses away from the CNS.
