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
Three differences between sensory neurone and motor neurone?
# Motor neurones have cell bodies inside the Central Nervous System (CNS) whilst in sensory neurones the cell body is located outside of the CNS # Motor neurones transmit impulses from the CNS to the effector which brings about a response to the situation, sensory neurones transmit impulses from to the CNS from the receptor. # Sensory neurones transmit impulses as a result of external stimuli such as pressure, light, temperature etc. Motor neurone transmit impulses passed along the CNS to the effector.
What is the connection between sensory nerves and the neurons in the brain?
Sensory nerves transmit information from sensory receptors in the body to the neurons in the brain. When sensory receptors detect stimuli such as touch, temperature, or pain, they send signals through sensory nerves to the brain. Neurons in the brain then process and interpret these signals, allowing us to perceive and respond to the sensory information.
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.
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
How may you Explain the role of sensory and motor neurones in a reflex arc.?

Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
What type of neuron's involved in a knee jerk?
sensory neurones motor neurones
How many synapses occur in this reflex arc?
there are 2 - one between the sensory and relay neurones; the other between the relay and motor neurones.

Type of neurones along a reflex arc?
the sensory receptor begins then the Relay neuron and final the motor neuron
What is the ascending nerve tract?
Nerve are bi-directional (they travel in both direction) as they carry both snesory and motor neurones (which are uni-directional). However the white matter (the part that carries the impulses) in the spinal chord can be split in two. The anterior part (front part) carries the descenging, motor neurones. These are better termed the Efferent neurones which means they are travelling away from the central nervous system (CNS). The posterior part (or back part) carries the ascending, sensory neurones. These are better termed Afferent neurones which means they are travelling towards the CNS. In short the "ascending" nerve tract is the part of the spinal chord that carries sensory neurones.
What are the two types of nerve?
sensory- receives information from environment motor- sends signals to muscles to allow you to move 1 other type of nerve is... autonomic - involuntary your welcome, j.m
