Otic vesicle chick, invagination of the otic placode occurs passively due to the movements of the surrounding placode. The otic placode in zebrafish, on the other hand, occurs by cavitation; the ectodermal placode condenses and forms an ovoid ball directly below the embryo surface. Otic vesicle formation occurs later, during the 25-30 somite stage in mice. 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
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
