A nociceptor ("pain receptor") is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals to the spinal cord and the brain.

Keratin and thickened plasma membranes of cells protect the skin against abrasion and penetration and glycolipids b/w its cells waterproofs this layer. 60 seconds . ; The anatomy of bones, Quiz 1 - Learn the anatomy of a human long bone. Composition and function of Keratinocytes. Celebrando Leonardo. Stimulus modality, also called sensory modality, is one aspect of a stimulus or what is perceived after a stimulus. Somatosensation occurs all over the exterior of the body and at some interior locations as well. Lateral inhibition is the process by which stimulated neurons inhibit the activity of nearby neurons.

Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch. They are responsible for the tactile sensitivity of the skin, so they were called tactile cells. Tactile Corpuscle Structure BIO201-General Senses . Search Tactile Corpuscle Location. The foliate and vallate papillae are considered large. glands that respond to rising androgen levels, , secrete sebum which helps keep hair from drying out and becoming brittle, forms a protective film that prevents excessive evaporation of water, keeps skin soft and pliable and inhibits the growth of certain bacteria. In lateral inhibition, nerve signals to neighboring neurons (positioned laterally to the excited neurons) are diminished. A sensation occurs when neural impulses from these receptors reach the cerebral cortex. Q. decreases, what effects does this have of diffusion?

Skin cells have different functional roles in their respective regions-the basal cell layer is the innermost layer of the epidermis, containing the keratinocytes and melanocytes. The oldest cells of the epidermis will be found here Lateral inhibition enables the brain to manage environmental input and avoid information overload. In general, these neurons have relatively large receptive fields (much larger than those of dorsal root ganglion cells). Dendritic cells (DCs), named for their probing, ‘tree-like’ or dendritic shapes, are responsible for the initiation of adaptive immune responses and hence function as the ‘sentinels’ of the immune system. Deep tactile mechanoreceptorsare found within the dermis of the skin, in the fascia surrounding muscles and bone, and in the periodontium. The epidermis is the outermost layer of the skin, and protects the body from the environment. A variety of receptor types—embedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular system—play a role. 42 terms.

Primates possess dermatoglyphics (the skin ridges responsible for fingerprints), but so do many other arboreal mammals. produce fibrous protein keratin; arise in stratum basale; these cells undergo continuous mitosis. A cell cube has 3cm/side, what is its: 1) surface area 2) volume 3) Simpliest ratio 1) 54cm2 2) 27cm2 3) 2:1 When a cell grows and it's S.A. to V.R. Most of Merkel's cells are found in sensitive areas of the skin - on the palms, feet, in erogenous zones. If the brain perceives the threat as credible, it creates the sensation of pain to direct attention to the body part, so the threat can hopefully be mitigated; this process is called nociception Tactile cells are specialized epithelial cells that stimulate specific sensory nerve endings when they are distorted by fine touch or pressure.-Excretion by means of secretion: Skin exhibits an excretory function when it secretes substances from the body during sweating.Sweating occurs when the body needs to cool off.
