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.
Do dendrites contain sensory neurons?
A dendrite is a part of a single neurone. All neurones (as far as I can remember) have dendrites. Do you mean Dorsal root ganglia? In which case yes.
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
What neurotransmitter neuron to muscle cell?
sensory neurones
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
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 neurotransmitter neuron to muscle cell?
sensory neurones
What is the input zone of a motor neuron?
dendrites
Carry messages from the CNS to the muscles and glands in the PNS?
Motor neurones
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.

Short branched extensions of a neuron?
In neurons, short, tapering, diffusely branched processes from the cell body are known as the dendrites. If the dendrites are short/tapering and diffusely branched, then this is referring to the dendrites of motor neurons.
