Sense Organs

encapsulated nerve ending that detects sustained touch, pressure, and stretch

sensory receptor that detects dissolved chemicals in the blood or extracellular fluid

cell in the cochlea that moves in response to incoming sound waves and alters generation of impulses in the auditory nerve

neuron with nerve endings surrounded by connective tissue or cells, which are sensitive to touch or vibration

encapsulated nerve ending that detects light touch in mucous membranes

sensory receptor that detects information from the external environment and is found throughout the skin and in the special senses

nonencapsulated nerve ending of a sensory receptor that is bare and not associated with another cell or tissue

nonencapsulated nerve ending of a sensory receptor that wraps around hair follicles and detects movement of the hair

sensory receptor that detects stimuli from the internal environment and is found in most internal organs

encapsulated nerve ending that detects vibration and deep pressure in the skin, joints, and some internal organs

biconvex transparent structure found posterior to the iris that bends light to focus on the retina

visible bump on the surface of the tongue that houses taste buds, typically on its upper surface

sensory receptor that detects mechanical stresses, including, pressure, touch, and stretch

sensory receptor that detects potentially damaging stimuli, such as intense heat, to which the brain initiates a negative response

sensory neuron with no sheath of connective tissue; includes nociceptors, thermoreceptors, and some mechanoreceptors

cranial nerve that transmits visual information from the retina to the brain

sensory receptor that responds to light

sensory receptor that receives mechanical stimuli about body positions and movements and is found in muscles, tendons, and ligaments

opening in the eye formed by the iris that changes diameter to control the amount of light entering the eye

innermost layer of the wall of the eye that contains a layer of pigmented cells, the photoreceptors, and neurons

cells in the peripheral nervous system that reacts to stimuli

have receptors found within complex organs of the head to detect senses of vision, hearing, equilibrium, smell, and taste

encapsulated nerve ending beneath the epidermis, especially in the palms and soles, that detects light touch

nonencapsulated nerve ending on a mechanoreceptor that detects general light touch

sensory receptor that detects changes in temperature

membrane that separates the outer and middle ear and transfers the incoming sound wave to the auditory ossicles of the middle ear

cranial nerve that transmits equilibrium sensory information from the inner ear to the brain
