Crocodilian form of crurotarsal ankle. The astragalus (pink) is fixed to the tibia (green) by a suture. Adapted with permission from Palaeos. In the type of crurotarsal ankle, which is found in crocodilians and some other archosaurs, the astragalus is fixed to the tibia by a suture, and the joint bends around a peg on the astragalus, which fits into a socket in the calcaneum.
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure.

The skin staple remover is a small manual device which consists of a shoe or plate that is sufficiently narrow and thin to insert under the skin staple. The active part is a small vertical blade that, when hand-pressure is exerted, pushes the staple down through a slot in the shoe, deforming the staple open into an 'M' shape to facilitate its ...
Bones are commonly described with the terms head, neck, shaft, body and base. The head of a bone usually refers to the distal end of the bone. The shaft refers to the elongated sections of long bone, and the neck the segment between the head and shaft (or body). The end of the long bone opposite to the head is known as the base.
Sutures: The skull bones are connected by fibrous joints called sutures. [1] In fetal skulls, the sutures are wide to allow slight movement during birth. They later become rigid (synarthrodial). Syndesmosis: Some of the long bones in the body such as the radius and ulna in the forearm are joined by a syndesmosis (along the interosseous membrane).
Absorbable sutures are used primarily within the body, rarely do they protrude through the skin (only thing I can think of is a modified subcuticular stitch used by plastic surgeons when the suture is inside the skin, and the ends are left external for tensioning).
For example, the skin is superficial to the bones, and the brain is deep to the skull. [1] Sometimes profound is used synonymously with deep . Medial and lateral , which describe a position that is closer to (medial) or farther from (lateral) the midline of the body.
