1) Tail of the Pancreas :
Tail of the Pancreas is narrow and usually lies in contact with the inferior part of the gastric surface of the spleen. It is present within the two layers of the splenorenal ligament together with the splenic vessels, to which it is closely related.
2) Tail of the Epididymis:
Epididymis consist of a tortuous canal which forms the first part of the efferent route from the testis. It consists of central region, or body, a superior enlarged head, and an inferior pointed end, the tail. The lateral surfaces of the head and tail of epididymis are covered by the tunica vaginalis and hence free.
3) Axillary Tail of the Breast (Tail of Spence) :
The Superolateral part of Breast is prolonged upwards and laterally towards the axilla, forming the axillary tail, which pass through the deep fascia to lie in close relationship to the pectoral group of axillary lymph nodes.
4) Tail of the Helix :
The cartilage of auricle of the external ear consists of a single piece of elastic fibrocartilage. This cartilage is absent from the lobule and between tragus and beginning of helix. Anteriorly, where the helix bends upwards, there is a small cartilaginous projection – spine of the helix. At its other extremity the cartilage is extended inferiorly as the tail of the helix. The tail of the helix is separated from the antihelix by the fissure antitragohelicina.
5) Tail of the Caudate Nucleus :
The caudate nucleus is an arcuate mass of gray matter which has a head, body and tail. The anterosuperior end is massive and termed head. At the interventricular foramen this narrows into body of the nucleus which tapers imperceptibly into the tail.
6) Tail of the Dentate Gyrus :
Dentate gyrus is a crenated strip of cortex. Anteriorly, the dentate gyrus is continued into the notch of the uncus, where it makes a sharp bend medially across the central part of its inferior surface. This transverse part is smooth and featureless, being termed the tail of the dentate gyrus (band of Giacomini), and it becomes indistinguishable on the medial aspect of the uncus.
7) Tailbone (Coccyx) –
Tailbone ( coccyx) is the terminal segment of the spine. It is a triangular bone that consists usually 3 to 5 rudimentary vertebrae fused together . The lower part of the filum terminale, also known as coccygeal ligament, inserts to the first segment. The coccyx is bordered anteriorly by the levator ani muscle and the sacrococcygeal ligament.
