How many nerve endings are in your hand?
There are about 17,000 touch receptors or nerve endings in a human hand, making it one of the most sensitive parts of the body. These nerve endings help us feel sensations such as pressure, temperature, and pain, allowing us to interact with our environment.
What at is a nerve stimulus?
A nerve stimulus is a signal or impulse that is transmitted along a nerve fiber, triggering a response in the body. This stimulus can be initiated by various factors such as touch, temperature, or pressure, and is essential for the communication between different parts of the nervous system.
Where would you find receptors that respond to?
You would find receptors that respond to various stimuli in different parts of the body, such as the skin for touch and temperature receptors, the nose for olfactory receptors, and the tongue for taste receptors. Additionally, there are receptors located in organs and tissues that respond to internal conditions like pressure, pH, and hormones.
What name of legs nerve?
The nerve that supplies sensation and movement to the leg is called the sciatic nerve. It is the largest nerve in the body and branches into smaller nerves that innervate different parts of the leg.
Which of these parts receive nerve impulses?
dendrites receive electrical and chemical signals from axon terminals.
The receptors for pain are?
Pain receptors are the types of nerve cell primarily responsible for taking and sending stimulation signals from different nerve endings to the brain, that will usually interpret then as pain. They are present in almost all parts of the body and respond to a broad range of stimuli.

Do Sensory nerve cells carry information from all sensory receptors to the immune system.?
Not all sensory receptors communicate with the immune system. Nerve cells carry information to various parts of the nervous system, eventually communicating with the brain or spinal cord.

Why are some parts of your body more sensitive than other?
some parts of the body, such as the face, contain more nerve receptors to carry sensations back to the brain than other parts of the body such as the heel of the foot.
Why are some parts of your body more sensitive than trhe others?
Some areas of the skin have a higher density of touch and other receptors so that they are more sensitive. For instance, your fingers need to have a good set of receptors so that you can feel and pick up fine things. The skin of your face needs a high density of receptors to help protect your eyes.

What is the function of kinesthetic receptors?
Kinesthetic receptors are responsible for detecting changes in body position and movement. They provide feedback to the brain about the body's orientation in space, allowing us to maintain balance and coordinate movement.
How does touch sensitivity in humans vary across different parts of the body?
Touch sensitivity in humans varies across different parts of the body due to differences in the density of touch receptors. Areas with a higher concentration of touch receptors, such as the fingertips and lips, are more sensitive to touch compared to areas with fewer receptors, like the back or legs. This variation in sensitivity allows us to perceive different levels of touch and pressure in various parts of the body.
Do sensory nerve cells carry information from all sensory receptors to the immune system?
No, sensory nerve cells primarily carry information from sensory receptors to the central nervous system (brain and spinal cord) for processing. The immune system receives information about potential threats from specialized cells called immune cells, such as lymphocytes and macrophages.
