a reflex
Reflex
No, not directly. Some sensory neurons can detect the effect of a motor neuron firing.
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.
You have several sensory receptors and they all measure differences in pressure, displacement, and movement. The main ones are the Merkle, Meissner, Pacinian, Raffini, Krause, Hair follicle receptors, and the pain receptors.
the sensory receptors for the eyes are the cornea and the optic nerve
The only response by the spinal cord is not an interpretation but a reflex. A sensory impulse comes in and at the cord a reflexive arc occurs taking information to muscles or glands. The brain does the interpretation. You touch a hot stove and that info goes to the spinal cord which causes a reflexive action where the muscles move the hand away. All that happens before the brain gets an "incident report".
they are called receptors.
The receptors of the eye are photo receptors, the ear has auditory receptors, the nose has olfactory (smell) receptors, the skin has tactile (touch)and thermo- (temperature) receptors and the tongue has gustatory (taste) receptors.
somatic receptors and special receptors
A stimulus activates sensory receptors in the body, such as on the skin or in the eyes, ears, nose, or mouth. These receptors then send signals through nerves to the brain, where the information is processed and interpreted, resulting in a sensory response.
Sensory nerves, or the receptor nerves, as they are only made up of sensory neurons. Receptors are the specialised structures at the end of the sensory nerves that receive the stimuli and convert it into an electrical signal to be conducted by the nerve as a nerve impulse.
Sensory receptors enable you to respond to stimuli in the environment of an organism. Some sensory receptors respond to taste and smell while others respond to physical stimuli.
