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
Where do motor neurons decussate?
Motor neurons decussate in the lower part of the medulla oblongata located in the brainstem. This is where the corticospinal tract crosses over, allowing motor signals from one side of the brain to control muscles on the opposite side of the body.
Which nerves from the brain are known to decussate?
The optic nerves and the pyramidal tracts are two examples of nerves that decussate, or cross over to the opposite side of the body, within the brain. This crossing of nerve fibers helps with the coordination of sensory and motor functions between the brain and the rest of the body.
Does a neurone a chloroplast?
Neurones are never in plants.It is a cell in animals.
What are bundles of neurones?
A nerve is a bundle of 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
What word means to cross over like the arms of an x?
Decussate

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.
Do Second-order neurons of ascending sensory pathways always decussate.?
No, second-order neurons of ascending sensory pathways do not always decussate. Some pathways decussate at the level of the medulla or spinal cord, while others do not cross over until reaching the thalamus. It depends on the specific sensory pathway and the type of information being transmitted.
What stores and secretes of neurotransmitter?
The axons of the neurones.
Where do motor neurons decussate?
Motor neurons decussate in the lower part of the medulla oblongata located in the brainstem. This is where the corticospinal tract crosses over, allowing motor signals from one side of the brain to control muscles on the opposite side of the body.
The cell which unerlies the entire nervous system?
They are neurones.
