What is the functio n of the spinal cord?
The spinal cord is a bundle of nerves, which serves the purpose of relaying sensory and motor messages between the body and brain. In the case of spinal cord injury, parts of the body are paralyzed when the motor messages from the brain cannot pass through the injury site on the spinal cord. Feeling is lost when sensory messages cannot pass the injury site to be processed by the brain.
How do nerves pass along messages throughout your body?
They send the messages along some cords ing your body from the brain to where ever, and then you do what they say.
What kind of nerves are in the upward tract and downward tract of the spinal cord?
The ascending tracts (upward) contain sensory nerves, that pass sensory information from the body to the brain. The descending tracts (downward) contain motor nerves that activate the muscles in the body according to the brain's "commands".
What kinds of nerves are in the upward tract and downward tract of the spinal cord?

Which direction do messages pass down the nerve cells?
Nerve impulses are carried by neurons and passed to other neurons at junctions called synapses. cells pass messages The signal may be directly transferred or can be carried across the gap by chemicals called neurotransmitters.
What is large bunch of nerves that pass through your bones?
The large bunch of nerves that pass through your bones are called the spinal cord. It runs through the spinal canal formed by the vertebrae of the spine. The nerves in the spinal cord carry signals between your brain and the rest of your body, allowing for sensory and motor functions.
These cells are able to pass messages back and forth?
Neurons are the cells responsible for sending and receiving messages in the nervous system. They can pass messages back and forth by transmitting electrical signals along their length and releasing chemical messengers called neurotransmitters at the synapses to communicate with other neurons or target cells.
Does a peripheal nerve pass from the spinal chord into the limbs?
Yes, peripheral nerves connect the spinal cord to the limbs and other parts of the body. These nerves carry messages between the brain and the rest of the body, allowing for movement and sensation.
Sensory input that does not pass through ------- in diencephalon?
cerebellum
How many functions of neurons in the nervous system?
Neurons are pathways for electrical messages to pass through. Their main function is to pass a message from one neuron to another. As a whole, they transmit these messages between a receptor (something that picks up a stimulus. A stimulus includes things such as temperature, pressure, pain etc.), the brain and an effector (something which carries out the response to the stimulus). There are three main types of neurons: Sensory neurons - receive message from receptor and transmit it to the -> Interneurons - receive message from sensory neurons and pass it on to the brain*. The brain responds and the interneurons pass the message on to the -> Motor neurons - receive message from interneurons and pass it on to an effector. *In the case of a reflex arc, where there is an unconscious response (e.g. touching a hot object) the message will bypass the brain and go straight from receptor to sensory to interneuron to motor to effector.
What body cells can pass electrical information?
Nerves
What is an example of sensory neurons?
An example of afferent neuron would be using a sense. In this case we will choose touch or feel. EX: Your Hammering the door and suddenly u smash a finger. First it started with a smash then that feeling passes through your sensory nerves which pass through your whole body ending at the brain which makes u feel pain. That is an afferent neuron experience.
