Otic vesicle Otic vesicle Otic vesicle, or auditory vesicle, consists of either of the two sac-like invaginations formed and subsequently closed off during embryonic development. It is part of the neural ectoderm, which will develop into the membranous labyrinth of the inner ear. This labyrinth is a continuous epithelium, giving rise to the vestibular system and auditory components of the inner ear. During the earlier stages of embryogenesis, the otic placode invaginates to produce the otic cup. Thereafter, the otic cup closes off, creating the otic vesicle. Once formed, the otic vesicle will reside next to the neural tube medially, and on
Body donation as medical schools, which teach anatomy using donated bodies. Under the Human Tissue Act, written consent must be given prior to death; consent cannot be given by anyone else after death. The Human Tissue Authority provides information to donors about where they can donate and answers many prevalent questions related to tissue donation on their website. The Human Tissue Authority provides the links to each establishment’s information, but each establishment has its own guidelines for body donation. The HTA also provides the tools to find donation sites local to the person wishing to donate their body, or tissues. Although most
