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 the connection between sensory nerves and the neurons in the brain?

Both use neurones which transmit in via action potential and synaptic transmission. Sensory neurones include pain neurones which enter directly into the brain, which perceives the stimulus as pain and gives emotional and motor responses accordingly. Sensory neurones also perceive homeostasis, in that they sense stimuli outside physiological norms and change homeostasis in order to rectify the problem. All motor and limbic (emotional) outputs from the brain are stimulated and therefore initiated by sensory neurone inputs. The spine relys information from peripheral sensory neurones to the brain, and is the literal connection between sensory neurones and the brain.


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 is the term for nerves carrying both sensory and motor fibers?

Mixed nerves are nerves that carry both sensory and motor fibers. These nerves enable bidirectional communication between the brain and various parts of the body, allowing for both sensory input and motor output to be transmitted.


Are spinal nerves primarily sensory or motor in function?

Spinal nerves have both sensory and motor functions. They carry sensory information from the body to the brain and transmit motor signals from the brain to the muscles to control movement.


Spinal nerves are purely sensory and motor?

Spinal nerves are mixed nerves, meaning they contain both sensory and motor fibers. Sensory fibers transmit information from the body to the brain, while motor fibers carry signals from the brain to muscles, glands, and other effector organs. This dual function allows spinal nerves to both receive sensory input and initiate motor output.


What nerve that contains fibers that both send and receive messages is called?

A mixed nerve, such as the trigeminal nerve, contains both sensory and motor fibers that can send and receive messages. These nerves are responsible for carrying both sensory information from the body to the brain and motor commands from the brain to the muscles.


Do nerves contain the axons of sensory and motor neurons?

Yes, nerves contain axons of both sensory neurons, which carry information from the body to the brain, and motor neurons, which carry instructions from the brain to the muscles and glands. The axons of sensory and motor neurons are bundled together within nerves to transmit signals throughout the body.


Are the limbs innervated by the motor and sensory neurons?

Yes, the limbs are innervated by both motor and sensory neurons.


Are the spinal nerve both sensory and motor?

motor


What type of nerve fibers are found in the ventral ramus of a spinal nerve?

The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.


Where can both sensory and motor fibers be found together?

Mixed nerves like the spinal nerves have both sensory afferents and motor efferents.


Does a mixed nerve contain both sensory and motor neurons?

Yes, "Mixed nerves" of the peripheral nervous system contain both sensory and motor fibers
