Anatomical Structure In Figure 1.1 shown below you can see the Anatomical Structure of the foot and the different bones that make up the Toes, or Phalanges as they are also known. As you can see from the image below, the metatarsals are connected to the Ankle bones via the Tarsometatarsal Joint. It is the Metatarsals however that the Phalanges attach to. The Proximal Phalanges are attached to the Metatarsals via the Metatarsophalangeal Joints which are the joints found at the base of the toes. The Metatarsophalangeal Joints are Condyloid Joints which allow various planes of movement. Flexion, Extension, Abduction, Adduction and Circumduction are the various movements that the Metatarsophalangeal Joint can perform. The structure of a Condyloid joint consists of an oval end of a bone that fits into a …show more content…

This type of joint allows for a good range of motion across two different axes. As we move further towards the distal end of the Phalanges we have another joint between the Proximal Phalanges and the Middle Phalanges. However, there are only four Middle Phalanges as the Big Toe or Hallux as it is also known consists of just a Proximal Phalanx and a Distal Phalanx. The joints between the Middle Phalanges and the Distal Phalanges are called the Proximal Interphalangeal Joints and these are the joints found in the middle of the toes. These joints are found on all toes with the exception of the Hallux or Big Toe which like the four other toes consists of the Distal Interphalangeal Joint which is the joint that is closest to the top of the toes hence the name Distal Interphalangeal Joint. There are a number of different muscles that allow the Toes or Phalanges to perform different actions and these consist of the Abductor Hallucis, Extensor Digitorum Longus and the Flexor Digitorum Longus. The Abductor Hallucis is a muscle on the inside the foot that spans from the Big Toe or Hallux to the Heel. The action of this muscle is to pull the Big Toe or

The bone was covered up inside a model of a stupa, or a Buddhist place of worship utilized for contemplation. The exploration group found the 1,000-year-old model inside a stone mid-section in a sepulcher underneath a Buddhist sanctuary in Nanjing, China. Inside the stupa model archeologists found the remaining parts of Buddhist holy people, including a parietal (skull) bone that engravings say had a place with the Buddha himself.

An articulation is the weakest point on the skeleton however the structure is capable of resisting strong forces that may threaten its normal alignment . A normal structure of a joint includes a coated layer of tough, slippery tissue that coats the ends of each bone known as an articular cartilage. A cartilage acts as a shock absorber and keeps the end of the bones from being crushed. For instance the knee, also known as the biggest and most complex joint in our body has an extra cartilage known as a semi-circular cartilages, these cartilages or menisci helps with the prevention of the femur to rock side to side on the tibia as well as acting as a shock absorber .

Structure Of The Foot: The structure of the foot comprises 26 mostly small bones and 33 joints which form two arches. These bones are held together by the fact that they fit into each other; and fibrous ligaments, muscles and a tough tissue (known as the plantar fascia) support them to retain the shape of the foot. There are also fat pads in the foot, which assist in absorbing impact and with weight bearing. The two major functions of the feet are that act as levers which push the leg forward to enable us to walk; and they help in maintaining body balance by being able to adjust to uneven surfaces.

The phalanges are not separately mobile, being bound by ligaments, so the claws from one functional whole. Its muscles work by means of contraction. They contain more retractor muscles than the extensor muscles. A retractor muscle, in sloth makes them cling onto the branches of a tree in a long period of time; they lack extensor muscles thus making it hard for

During the Renaissance health and medicine changed considerably . There were many important changes to the understanding of anatomy and surgery. Important doctors and surgeons discovered different ways of understanding to body and different ways of operating. For example how Vesalius in the 15th century dissected the human body to learn more about anatomy. During this essay I will investigate how far health and medicine improved during the Renaissance by focusing on anatomy and surgery.

Andreas Vesalius (1514-1564), a physician and anatomist, cited one of the greatest publication on antiquated anatomy in the early modern period “De Humani Corporis Fabrica Libri Septem”. This book challenged the views of anatomical structure and practices known in ancient times comparing both female and male internal structures. As for his perspective, Vesalius introduces new challenges as to how to interpret physical anatomy through dissection, retrieving not only interest but most importantly scientific discovery in both subjects. He approaches this proceeding matter in untraditional statements in order to interpret external and internal features with detailed anatomized precision. Representing both sexes, he follows with illustrations and analogies uncovering the

The three ear bones of the middle ear are in only a few animals, and the way that they are present in humans in much different from other animals. The three ear bones are the malleus, the incus, and the stapes. The malleus and the incus formed from the transition of reptile to mammal, and in the reptile, they originally made up jawbones, as years went on, they formed into a bone in the ear for humans. The stapes formed from the transition of fish to amphibian to human, and in the fish, the stapes was the hyomandibula, a large rod that connects the upper jaw the brain case. The stapes, through evolution, formed into an ear bone.
