sense organ

A specialized organ or structure, such as the eye, ear, tongue, nose, or skin, where sensory neurons are concentrated and that functions as a receptor. Also called sensor.

sense organ

A sensory receptor; a structure consisting of specialized sensory nerve endings that are capable of reacting to a stimulus (an external or internal change) by generating nerve impulses that pass through afferent nerves to the central nervous system. These impulses may give rise to sensations or reflexly bring about responses in the body.

sense organ

any receptor of external or internal stimuli.

sense organ

A structure especially adapted for the reception of stimuli and the transmission of the relevant information to the brain. The organ of sight is the eye, in which light is transduced into nerve signals in the photoreceptors of the retina.

This is especially so, even among persons age 65 or over, for circulatory diseases, mental disorders, and to a lesser extent, injuries and poisonings and the nervous system and sense organs. For circulatory diseases, hospital expenditures decrease from 59 percent of total expenditures at 65-74 years to 29 percent at ages 85 or over, while nursing home spending increases from 9 to 54 percent of the total.

The apical ganglion (AG) of molluscs (Leise, 1996; Lin and Leise, 1996a, b; Marois and Carew, 1997a, b) is also known by a variety of other names, e.g., apical sense organ (Conklin, 1897), apical organ (Pelseener, 1911; Werner, 1955; Tardy, 1974; Page, 1992), cephalic sensory organ (Bonar, 1978; Uthe, 1995), apical sensory organ (Chia and Koss, 1984; Kempf et al., 1997), and apical complex (Tardy and Dongard, 1993).
