How do the types of neurons found in the CNS and pns differ in their function?
Sensory (afferent) neurons conduct sensory information toward the CNS.The brain and spinal cord contain interneurons. These receive information and if they are sufficiently stimulated, they stimulate other neurons.Motor neurons (efferent neurons) send information from interneurons to muscle or gland cells (effectors).
How does the brain send messages to the body systems?
The messages in you brain are transmitted by nerve cells which are known as neurons. There are efferent and afferent neurons which perform this function.
What part of the nervous system is responsible for the reflex arc?
The peripheral nerves and the spinal cord. When a reflex starts, the peripheral nerves in the arms or legs send a signal to the spinal cord. Normally that signal is sent on to the brain for processing. In a reflex, the spinal cord itself sends a response back to the arm or leg to move immediately.
What are the afferent fibers that go to cerebellum?
2 types of afferent fibres that arise from spinal cord and brain-stem are climbing fibres and mossy fibres.climbing fibres :from contralateral inferior olivary nucleus (in medulla)make excitatory synapses directly on purkinje cellsmossy fibres :from all other structures that send fibres to cerebellum (ex. spinal cord)influence purkinje cells indirectly through excitatory synapses with granule cells
What respond to a stimulus that does not involve the brain?
It is called a reflex and does not involve the brain, but instead, the spinal cord. So, in effect, the spinal cord can also 'think' and process information, though not quite the level of complexity as the brain, especially the cerebral cortex. But, that is a good thing. If I touch a hot stove, my spinal cord will send out a signal to pull my hand off well before my 'brain' feels the heat. There is a lot of survival value to reflex arcs that are essential to survival that do not include the brain.
Which neurons transmit information to the brain and spinal cord?
Sensory neurons gather information and send it to your spinal cord.
What pick up the stimuli and send it to the brain or spinal cord?
Neurons, or nerve cells, pick up the impulses and send them to other neurons through axons and dendrites until it reaches the spinal cord.
Which neurons send messages to the spinal cord and brain?
Interneurons send messages from the spinal cord to the brain.
Where is the signal to transferred to the association nerve cells?
The signal comes from the brain, down the spinal cord, and down to the nerve cells that need to send the stimulus signal. The signal also runs vice versa, up the spinal cord and into the brain.
Does the spinal cord send messeges to the brain?
No the nerves in the spinal cord send the messages to the brain. Not the actual spinal cord.
What is the fuction of the spinal cord?
the spinal cord help send signal down or up from the brain to the limbs
What is the brain to the spinal cord?
the spinal cord is used to send messages around the body from the brain ie use left hand and arm to wave etc...
Why spinal cord runs through middle of your back bone?
Because it have to send message to (CNS)
What is the name of the cord tat send messages in the brain?
SPINAL?
What the does brain stem connect the brain to?
The brain stem connects the brain to the spinal cord, so that the brain can send messages through the cord to the rest of the body. The functioning of the body is severely compromised if the spinal cord connections are severed.
White matter of the spinal cord contains?
The H-shaped grey matter of the spinal cord contains motor neurons that control movement, smaller interneurons that handle communication within and between the segments of the spinal cord, and cells that receive sensory signals and then send information up to centers in the brain.
What constitutes the central nervous system?
The CNS is the brain and the spinal cord. Has a complex network of neurons that work to send, receive, and interpret information.
