What are the sensory nerves?

Sensory nerves are the blood vessels of the peripheral nervous system that carry signals towards the brain in response to stimuli. Such stimuli may be environmental as at temperature changes; provide stimuli about touch such as texture; include injuries, as in a feeling of pain; or relate to the state of the internal organ. They are distinguished from motor nerves, blood vessels that carry impulses from the brain to the muscles and tell them to move. Sensory nerves transmit what is called afferent signals that the brain receives and responds appropriately. Stopping from the spinal cord, the component of the central nervous system, to the receptor cells throughout the body, almost all tissues of the body penetrate. They also tend to be paired with motor nerves, which are referred to as effect because they transmit nerve pulses from the central nervous system. For Example, after affecting hot stoves, sensory receptors at your fingertips quickly send a message along the nerves to the brain and tell the brain that this stimulus is hOrsk and painful. In response to this, the brain sends an impulse along the motor nerves that innervate the relevant arm and hand muscles, causing them to download quickly and pull the hand.

Within the sensory nerves, nerve cells are tied in fibers and ends receptors that can be classified according to their function. For example, nociceptors are those who warn the brain of injury and create pain, while photoreceptors react to light and mechanoreceptors respond to touch and pressure. In addition, olfactory receptors in the nose detect odors, while the taste receptors on the tongue detect flavors in the diet.

sensory nerves transmit messages from these receptors through electrical signal known as the nerve pulse. Nerve pulses are made towards the nerve roots, a place where the sensory nerves enter the spinal cord and from the spinal cord to their respective center in the brain. The brain is then responsible for the interpreThe tacing of these messages, such as whether the surface that is browsing through the foot is safe. Once the stimuli are accepted and interpreted in the brain, it determines the appropriate answer. He then sends the message back down to the spine, out through the motor nerves and to the relevant muscles and tells them to move accordingly.
