Sensory receptors in the dermis include: free nerve endings, pacinian corpuscles, and hair follicle receptors The mechanoreceptors of the skin are the meissner's corpuscles (which respond to light touch), the pacinian corpuscles (deeper in the dermis and respond to pressure), and the merkel's disks (closely related to the merkel's cells located in the epidermis and respond to light touch). The nociceptors are pain receptors that recognize hot, cold, and pain.
Meissner's corpuscles; pain and touch receptors, Pacinian corpuscles; pressure receptors, hair follicle receptors; light touch receptors, Rufini's corpuscles; respond to deep pressurethat recieve the stimulus
Sensory receptors gather information that is further processed by your brain. They tell your brain when it is getting cold, warm, wet, dry etc. Sensory receptors also tell your body when you are in danger. If you cut yourself, burn yourself, any damage to the body, and they will respond accordingly to prevent further damage.
Meissner's corpuscles and hair follicle receptors
Mechanoreceptors are sensory receptors that respond to mechanical pressure or distortion. They are responsible for detecting sensations like touch, pressure, vibration, and proprioception. Examples of mechanoreceptors include Merkel cells, Meissner's corpuscles, Pacinian corpuscles, and hair cells in the inner ear.
Tissue from a hair follicle that is still attached to the root end of hair
Whilst all of these things are within the dermis of the skin, the arrector pili is the odd thing out. The arrector pili is a muscle where as the rest (meissner, pacinian and merkel) are nerve endings. The result of contraction of arrector pili is the standing up of a hair. The meissner corpuscle is a sensory nerve ending that is specific for fine touch, as are merkel cells [light touch]. The pacinian corpuscle is a nerve ending specific for sensation of deep pressure and vibration.
Hair is to protect our bodies from the elements, helps regulate heat and is a sensory item this is why each hair follicle has nerve endings attached. Its also there to look pretty! Pubic hair is also there to stop skin from rubbing.
The structural and cellular features of a hair follicle include the papilla, root sheath, matrix, bulge, and hair fiber. The arrector pili is another hair structure that is a very small muscle fiber attached to the follicle.
the hair follicle is a skin organ that produces hair.
The root of each hair follicle is connected to the small arrector pili muscles are small muscles attached to hair follicles in mammals. Each arrector pili muscle has a bundle of smooth muscle fibers which attach to the follicular units which have nerves.
The root is part of hair embedded in the follicle in dermis. It has an attached smooth muscle which can contract causing the hair to stand up right. This causes the skin to form a slight bump which we call a 'goose bump'.
