No, nerves do not send signals. They transmit signals produced by receptors or the brain or spinal cord.
Autonomic
to send signals through the body when you touch something hot
Different stimuli trigger sensory nerves. Such stimuli may include temperature, pressure, vibration, touch, and pain. In answer to your question, nothing sends messages to your sensory nerves. What happens is that these nerves send signals to your brain which then interprets the signals as pain, pleasure, etc. as stated above, never receiving messages.
No. Not even from the ears. It's a chemical process.
Usually nerves have good capacity to send signals. These signals are send by depolarization waves across the nerve fibers. For re polarization of the nerves, energy is required and if impulses has to be sent more repeatedly than energy can be generated by cells, there will nerve fatigue, for example after an attack of Fit.(Seizer attack.)
What 12 structures receive and send sensory and motor signals between the body and brain
The sensory nerves in the skin, called cutaneous nerves, transmit messages to the brain about touch, pressure, temperature, and pain. These nerves have receptors that respond to different stimuli on the skin and send signals to the brain for processing.
Nerves and brain cells in the brain send electric signals to each other to tell the body what to do.
The nerves in the skin detect sensations like touch, temperature, and pain. When stimulated, these nerves send electrical signals to the brain through the spinal cord. The brain then interprets these signals as specific sensations, allowing us to feel and respond to our environment.
The eyes (vision), ears (hearing), nose (smell), and tongue (taste) send nerves directly to the brain to process sensory information. These sense organs have specialized receptors that detect stimuli from the environment and convert them into signals that are transmitted to the brain for interpretation.
Nerves tell glands when to release chemicals. Nerves send messages to glands. Apex- Nerves instruct glands to send out hormones.
There are multiple types of sensory nerves in the body, including those responsible for touch, pain, pressure, temperature, and proprioception. These sensory nerves send signals to the brain to provide information about the environment and help with perception and coordination.
