Sensory neurons
the gate keeper of human brain is thallamus which is the floor of dihensephallon. It sort out the outgoing impulse from brain and incoming impulse from spinal cord.
The brain stem
When you are stung by a bee you don't feel it until the impulse reaches your brain. The signal travels along your nerves to your spinal cord, where it is turned into a chemical message and sent to your brain.
Nerve impulses travel up through nerves, into the spinal cord and into one of the different lobes of the brain depending on where the impulse comes from. For example, if the impulse comes from your ear, the impulse would travel to the temporal lobe.
A nervous impulse begins in the dendrites of a neuron, travels through the cell body and axon, and then is passed on to the next neuron via a synapse. This sequence repeats until the impulse reaches its destination, such as a muscle or gland, where it triggers a response.
A reflex. Reflexes are processed by the spinal cord in order to provide a quicker reaction than would be achieved if the signal travelled all the way to the brain and back.
The spinal cord is a structure that starts at the brain and extends down the back within the spinal column. It serves as a pathway for nerve signals traveling between the brain and the rest of the body, controlling movement, sensation, and other functions.
Meningitis enters the brain through the bloodstream or by direct contact with the brain and spinal cord. Once inside, the infection causes inflammation of the protective membranes surrounding the brain and spinal cord, leading to symptoms such as headache, fever, and neck stiffness.
The spinal cord is a nerve cord inside the spine traveling all the way to the brain, so if you didn't have the nerve cord you're brain couldn't send/receive messages to the body
The initial sensory receptor detects a change e.g temperature. This is sent as an electrical impulse via a series of sensory receptors to the spine, if there is a problem a reflex occurs. If there is no problem the impulse is transmitted to the brain through the spinal cord.
