What are bundles of neurones?
A nerve is a bundle of neurones
What carries information to the brain to be interpreted?
Sensory Neurones
What type of neuron's involved in a knee jerk?
sensory neurones motor neurones
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 is a bundle of neurones?
Synapse
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
Similarities of motor and sensory neurons?
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.
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.
What stores and secretes of neurotransmitter?
The axons of the neurones.
What is the system's reaction to the stimulus?
Stimulus detected by receptors, transmitted to brain via afferent neurones, info processed at brain, efferent neurones, then to affector such as muscles.
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.
The cell which unerlies the entire nervous system?
They are neurones.
