What's in a nerve? Receptors are groups of specialised cells. They can detect changes in the environment, which are called stimuli, and turn them into electrical impulses. Receptors are often located in the sense organs, such as the ear, eye and skin. Each organ has receptors sensitive to particular kinds of stimulus.

Endocrine System They can only stimulate target cells, because they are the only cells that have the necessary components to respond to action/movement from the hormone. Most of the cells have to have special receptors in order to receive the signal from the hormones, and if a hormone comes to a non-applicable cell, it will be denied.

- Receptors that detect temperature are made up of free nerve endings on the skin and are called thermoreceptors. Pain receptors on the skin are also free nerve endings called nociceptors.Cutaneous mechanoreceptors are probably the first type of skin receptors that come to mind for most people.he finger tips are densely packed with receptors. Thermoreceptors respond to temperature on the skin, such as from an ice cube. Human skin. Mechanoreceptors are involved in the body's sense of balance. One type of touch receptor found in the skin are call Meissner's corpuscles.

Source(s):or the tongue, it is more complicated. There are two types of receptors, the pressure sensitive receptors (general somatic afferent) and the chemical receptors (special sensory afferent). The chemical receptors which are located on your taste buds recognize 4 different tastes, sweet, sour, salty and bitter.

Understanding Hormone Receptors and What They Do Cell receptors, including hormone receptors, are special proteins found within and on the surface of certain cells throughout the body, including breast cells. These receptor proteins are the “eyes” and “ears” of the cells, receiving messages from substances in the bloodstream and then telling the cells what to do.In other words, the receptors act like an on-off switch for a particular activity in the cell.hese receptor proteins are the “eyes” and “ears” of the cells, receiving messages from substances in the bloodstream and then telling the cells what to do.

Understanding Hormone Receptors and What They Do If the right substance comes along that fits into the receptor — like a key fitting into a lock — the switch is turned on and a particular activity in the cell begins. One type of receptor found in normal breast cells is the hormone receptor. By attaching to hormone receptors, estrogen and/or progesterone contribute to the growth and function of breast cells.

Hormones, Receptors and Target Cells A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.Reception of a radio broadcast provides a good analogy.ormone receptors are found either exposed on the surface of the cell or within the cell, depending on the type of hormone. In very basic terms, binding of hormone to receptor triggers a cascade of reactions within the cell that affects function.

T-cell lymphocyte These cells can be distinguished from other types of lymphocytes (B-cells) by the receptor on the outside of their cells called the T-cell receptor (TCR). This receptor allows T-cells to identify specific antigens (foreign substances) that enter the body.

Food_and_Nutritional_Toxicology Cells must have specific membrane or intracellular receptors to which hormones can bind. Target cell response depends on three factors: blood levels of the hormone, relative numbers of target cell receptors, and affinity of the receptor for the hormone.ndocrine glands may be strictly endocrine, such as the pituitary, thyroid, parathyroid, adrenal, pineal and thymus; or they may be organs that have hormone production as one of many functions, such as the pancreas, gonads, hypothalamus, and others.

- Abstract. Hair cells are the sensory receptors in the inner ear that detect sound and head motion to begin the processes of hearing and balance control. The defining feature of hair cells is the hair bundle, the transduction organelle protruding from their apical surface composed of ordered arrays of stereocilia.

Receptor Biology: Steven M. Sine Receptors are nature's transducers—they detect circulating hormones or substances released by nerve activity and elicit a biological response.Our research centers on specialized types of receptors called synaptic receptors, found on the surfaces of cells in close proximity to nerve terminals.f the receptor is located on a muscle cell, the impulse triggers contraction. Whereas if it is on a nerve cell, it causes release of transmitter substance on yet another cell. In this way, excitable cells communicate throughout the body by means of specialized pairs of neurotransmitter substances and receptors.

sensory receptors sensory receptors. The Oxford Companion to the Body. © The Oxford Companion to the Body 2001, originally published by Oxford University Press 2001. sensory receptors account for our ability to see, hear, taste, and smell, and to sense touch, pain, temperature, and body position. They also provide the unconscious ability of the body to detect changes in blood volume, blood pressure, and the levels of salts, gases, and nutrients in the blood.
