A peg cell is a non-ciliated epithelial secretory cell within the uterine tube (oviduct or fallopian tube). [1] These cells represent one of three epithelial cell types found within the normal fallopian tube epithelium and only make up around 10% of the total number of cells. The other two cell types are ciliated columnar and intercalary cells. [1]

Intraglomerular; Extraglomerular; Juxtaglomerular cell; Macula densa cell; Stromal cell → Interstitial cell → Telocytes; Kidney proximal tubule brush border cell; Kidney distal tubule cell; Connecting tubule cells; α-intercalated cell; β-intercalated ...
Dental anomalies are among the most recognizable features of ED, with common findings including hypodontia (missing teeth), oligodontia (absence of six or more teeth), and anodontia (complete absence of teeth). Teeth that are present often exhibit unusual shapes, such as conical or peg-like forms, particularly in the anterior regions of the mouth.
It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes , eyelids , ears , inside the nose , inside the mouth , lips , the genital areas , the urethral opening and the anus .
The central part of the otic vesicle represents the membranous vestibule, and is subdivided by a constriction into a smaller ventral part, the saccule, and a larger dorsal and posterior part, the utricle. The dorsal component of the inner ear also consists of what will become the semicircular canals. The utricle and saccule communicate with ...
Stereocilia (or stereovilli or villi) are non-motile apical cell modifications.They are distinct from cilia and microvilli, but are closely related to microvilli.They form single "finger-like" projections that may be branched, with normal cell membrane characteristics.
In regions such as the gingiva and parts of the hard palate, oral mucosa is attached directly to the periosteum of underlying bone, with no intervening submucosa. This arrangement is called a mucoperiosteum and provides a firm, inelastic attachment. [12] A variable number of Fordyce spots or granules are scattered throughout the nonkeratinized ...
There are two types of hair cells specific to the auditory system; inner and outer hair cells. Inner hair cells are the mechanoreceptors for hearing: they transduce the vibration of sound into electrical activity in nerve fibers, which is transmitted to the brain. Outer hair cells are a motor structure.
