Motor neuron dendrites can vary significantly in length, typically ranging from a few micrometers to several centimeters, depending on the specific type of motor neuron and its location in the body. The extensive branching of dendrites allows them to receive inputs from multiple sources, facilitating complex signaling. In general, the overall length and structure of dendrites contribute to the neuron's ability to integrate and process information effectively.
What else can I help you with?
Why do the sensory neuron has short axon and long dendrites?
sensory and motor neurons are sometimes very long so that the impulses can be carried away from the body very quickly. in the motor neuron the impulses "jump" over the fatty tissue to the Node Of Ranvier.
How may you Explain the role of sensory and motor neurones in a reflex arc.?
what is the role of sensory and motor neurones in a reflex arc
Which way does a dendrite conduct nerve impulses to the cell body?
the dendrites pick up msgs from other neurons lying nearby.they pass the msg to the cellbody, and then along the axon, the axon might then pass it on to another neurones. from the receptorto the sensory neuron to the relay neurons to the motor neuron to the muscle
What type of cell can be centimeters in length?
There are very few.Some neurones are upto 3m long.
Do dendrites contain sensory neurons?
Yes, dendrites are extensions of nerve cells that receive signals from other nerve cells. Sensory neurons, which carry sensory information from the peripheral nervous system to the central nervous system, have dendrites that receive stimuli from the environment and transmit them as electrical impulses to the cell body.
Why does the body have both sensory and motor neurones?
the body has both sensory and motor neurones because the sensory neurones sense what is happening and sends the message along and like a motor the motor neurones pass on the message constantly round and round until it reaches its destination

What type of neuron's involved in a knee jerk?
sensory neurones motor neurones
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.

What is the input zone of a motor neuron?
dendrites
Muscular movement is caused by what neurons?
Muscular movement is caused by the contraction Actin and Myosin grids. This is stimulated Motorneurones (Efferent neurones is also a commonly used term which means neurones traveling away from the CNS). The motor neurones can be one of two kinds, determined only by their targets as they have no structural difference, Somatic Motor or Autonomic Motor. Somatic motor neurones are the ones that innervate the Skeletal Muscle and are thus under Voluntary Control. This is the type of muscle most people will think of if they heard you question and so it is concievable that the autonomic motor neurones will be overlooked. These neurones control the Smoothe Muscle, like the organs within the body, and as it would take too much concentration to actively control all your bodily functions these are not under voluntary control. In short the general term used to describe a neurone that stimulates muscular contraction is called a motor neurone, or more specifically Somatic Motor Neuron or Autonomic Motor Neurone.

In which direction do motor neurones carry electrical impulses?
up the bum and around the hole

Describe motor development?
Motor development is the development of strength, speed and precision in the use of speech organs, hands, fingers, arms and legs and other bodily muscles. Sumaira Pakistan
What is the basic unit of structure and functon of the nervous system?
The nervous system is used to trasmit information around the body. It is made of two systems: the central nervous system (which consists of the spine and brain) and the peripheral nervous system (which consists of neurones and receptors). There are three types of neurones: sensory neurones, relay neurons, and motor neurones.
