Sensory Epithelial Tissue
Sensory epithelial tissue is built from a modified form of columnar cells together with elongated neurosensory cells, and carries fine sensory hairs at its free end.
Function: perceiving both external and internal stimuli.
Location: found in the nose (as the olfactory epithelium), the ear (as auditory hair cells) and the eye (as photoreceptors). …
What this figure shows. A cross-section of the nasal olfactory region: an epithelial layer (resting on a bony cribriform plate below) made up of slender receptor cells bearing fine cilia at their free (upper) surface and a thin dendrite running down to a cell body, flanked by taller supporting cells; the receptor cells' basal processes (axons) collect and pass through the cribriform plate into a rounded olfactory bulb, where they synapse on a mitral cell before co …
