What is the tissue that directs how and when muscles move?
The nervous system, specifically the brain and spinal cord, directs how and when muscles move through the transmission of electrical signals called nerve impulses. These impulses travel along motor neurons from the central nervous system to the muscles, triggering muscle contraction and movement.
Where do impulses travel?
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.
How does information travel from the brain to the lower extremities?
Information travels from the brain to the lower extremities through use of the peripheral nervous system. A signal is sent from the brain through the spinal cord and into muscles of the trunk.
Path way of the message to the nervous system?
The stimuli will be picked up by the sensory neurons then nerve impulses travel to your spinal cord. Those nerve impulses return to motor neurons that will react (like you pull your hand away, or you yell) as you react the nerve impulses travel to your brain.
Where do nerve impulses travel?
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.
If the ventral roots are destroyed can impulses reach the spinal cord?
In short, Yes.A majority of the "signals" that travel through the ventral roots are motor "signals" going out to the periphery from the spinal cord. As such, the signals have already "reached" the spinal cord from the brain or another region of the spinal cord.Thus, A ventral root lesion will interrupt signals from reaching the periphery.
How are messages from the femoral nerve sent to the brain?
Messages from the femoral nerve are sent to the brain through a series of electrical impulses. These impulses travel along the nerve fibers of the femoral nerve until they reach the spinal cord, where they are then transmitted up to the brain via the spinal cord's sensory pathways. Once in the brain, the messages are interpreted and processed to produce a response or sensation.
What relays impulses between the brain and the other body parts?
The nervous system relays impulses between the brain and other body parts through nerve cells called neurons. These neurons communicate through electrical signals that travel along nerve fibers to transmit information throughout the body.
How fast nerve impulses travel?
Nerve impulses travel through nerve fibers, and the speed of which they travel depends on the type of nerve fiber. They travel usually around 86 miles per hour.
How do brain send signals to all of your body?
The brain sends signals to the body through the nervous system, which is composed of neurons that transmit electrical impulses. These signals travel through the spinal cord and peripheral nerves to communicate with muscles, organs, and glands, controlling various bodily functions and movements. This complex network allows the brain to regulate and coordinate all activities in the body.
What form sensory impulses?
Sensory impulses are typically in the form of electrical signals that travel along nerve fibers from sensory receptors to the brain or spinal cord. These impulses carry information about sensations such as touch, temperature, pain, and pressure. The brain then processes these impulses to generate a conscious perception of the sensory input.
What circuit types is exemplified by impulses that travel from a single neuron of the brain and activate a hundred or more motor neurons in the spinal cord?
Diverging circuits
