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. They contain actin.
There are two different types of fluid that surround the hair cells of the inner ear. The endolymph is the fluid that surrounds the apical surfaces of hair cells. Potassium is the major cation in the endolymph and is thought to be responsible for carrying the receptor currents in the cochlea .
It is estimated that 1 in 3 domestic dogs will develop cancer, which is the same incidence of cancer among humans. [2] Dogs can develop a variety of cancers and most are very similar to those found in humans. Dogs can develop carcinomas of epithelial cells and organs, sarcomas of connective tissues and bones, and lymphomas or leukemias of the ...
Ceruminous adenocarcinoma is a malignant neoplasm derived from ceruminous glands of the external auditory canal.This tumor is rare, with several names used in the past. [3] [4] Synonyms have included cylindroma, ceruminoma, ceruminous adenocarcinoma, not otherwise specified (NOS), ceruminous adenoid cystic carcinoma (ACC), [1] [2] and ceruminous mucoepidermoid carcinoma.
Transitional cell carcinoma, a type of cancer most commonly seen in a dog's bladder, may respond to ivermectin in the same way as human renal cell carcinoma. Unfortunately, there is not yet any ...
A kinocilium is a special type of cilium on the apex of hair cells located in the sensory epithelium of the vertebrate inner ear. Contrasting with stereocilia, which are numerous, there is only one kinocilium on each hair cell. The kinocilium can be identified by its apical position as well as its enlarged tip. [1]
Mast cell tumor on lip of a dog. Veterinary oncology is a subspecialty of veterinary medicine that deals with cancer diagnosis and treatment in animals. Cancer is a major cause of death in pet animals. In one study, 45% of the dogs that reached 10 years of age or older died of cancer. [1]
Studies researching damaged dark cells due to genetic abnormalities or therapeutics are very important in attempting to understand the onset and mechanism of said balance impairments. [9] Dogs have been used as models due to similarities between humans and dogs with regards to inner ear size, inner ear lesions and susceptibility to ototoxins. [9]
