The heel's skin is the least sensitive skin on the human body (according to mass ballot-type study). This only applies to most people and studies may show that other people may find other skin to be least sensitive. Other results are; elbow, hand, finger, earlobe. This is really an irrelevant study as some people may experience things in other ways as others. Some people are most ticklish under their feet, others are more ticklish under their arms, tummy, neck or legs. Which part of the body is the least sensitive requires for an opinionated answer, and no straight answer.
What else can I help you with?
The size map of each body part in the postcentral gyrus is determined by?
The size map of each body part in the postcentral gyrus is determined by the density of sensory receptors in that body part. Areas with more sensory receptors, such as the hands and face, have larger representations in the postcentral gyrus compared to areas with fewer sensory receptors. This organization is known as somatotopy.
The part of the integumentary system that contains sweat glands and sensory receptors?
The layer of the integumentary system that contains sweat glands and sensory receptors is the dermis. This layer is located beneath the epidermis and plays a crucial role in regulating body temperature and providing sensory information to the brain.
Which part of a reflex arc would have a cell body in the posterior root ganglion?
The sensory (afferent) neuron has a cell body located in the posterior root ganglion of the spinal nerve. This neuron carries sensory information from the peripheral receptors to the central nervous system.
Which area of the body has the most sensory structures?
The fingertips have the highest density of sensory structures, such as touch receptors and nerve endings. This high concentration of sensory structures allows for precise discrimination of touch and texture.
What is the Sensory receptors that respond to movement?
propriocepters respond to the movement of the body. cerebellum is responsible for the subconcious movement of the skeletal muscles. the primary motor cortex is a cortical site involved with controlling movements of the body. movement is part voluntary control.

Cutaneous sensory receptors that reside in the skin are part of what system?
Cutaneous sensory receptors in the skin are part of the somatosensory portion of the nervous system.

The layer of the integumentary system that contains sweat glands and sensory receptors is the dermis. This layer is located beneath the epidermis and plays a crucial role in regulating body temperature and providing sensory information to the brain.
What are general sensory receptors?
they are the growth bubbles on the backs or spine of the living creature. the sensory part are the part which help its helper to sense what is happpening with the body. kind of like another brain...... the receptors revieve the brain waves from the actual brain to feed its knowledge to the sensory like bubbles. need more info email me at Stamos@yahoo.com
Which part of a reflex arc would have a cell body in the posterior root ganglion?
The sensory (afferent) neuron has a cell body located in the posterior root ganglion of the spinal nerve. This neuron carries sensory information from the peripheral receptors to the central nervous system.
What body system includes the brain spinal cord and sensory receptors?
The peripheral nervous system, contains all the nerves in the body that lie outside of the spinal cord and brain. They also relay signals from sensory receptors that monitor external conditions to the central nervous system.
What reflexes result from the stimulation of sensory receptors in the skin?
The stimulation of sensory receptors in the skin can lead to various reflexes, including the withdrawal reflex and the stretch reflex. The withdrawal reflex occurs when a painful stimulus is detected, prompting an immediate withdrawal of the affected body part to protect it from injury. Additionally, sensory receptors can trigger other responses, such as the stretch reflex, which helps maintain posture and balance. These reflexes are mediated by the nervous system and help the body respond quickly to environmental changes.
Which area of the body has the most sensory structures?
The fingertips have the highest density of sensory structures, such as touch receptors and nerve endings. This high concentration of sensory structures allows for precise discrimination of touch and texture.
Which type of nerve cells only carry impulses toward the body of the cell?
Sensory neurons are the type of nerve cells that carry impulses only towards the body of the cell. They transmit sensory information from receptors in the body to the central nervous system for processing.
Stepping on a drawing pin with bare feet from this what is the receptors?
Stepping on a drawing pin activates nociceptors, which are sensory receptors responsible for detecting pain. These receptors send signals through sensory neurons to the spinal cord and brain, alerting you to the injury. Additionally, mechanoreceptors may be involved in sensing the pressure and texture of the pin. This rapid response is part of the body's protective mechanism to withdraw from harmful stimuli.
What is the Sensory receptors that respond to movement?
propriocepters respond to the movement of the body. cerebellum is responsible for the subconcious movement of the skeletal muscles. the primary motor cortex is a cortical site involved with controlling movements of the body. movement is part voluntary control.
What part of the body might have the smallest simultaneous spatial threshold?
The part of the body with the smallest simultaneous spatial threshold is typically the fingertips. This area has a high density of sensory receptors, particularly mechanoreceptors, which allows for acute sensitivity to touch and fine discrimination of spatial details. The proximity of these receptors enables the fingertips to detect small changes in texture and pressure with great precision.
