The structure of the hand
The structure of the hand is made up of bones muscles, tendons and ligaments joints and nerves. The bones of the forearm are the ulna and radius.
The hand is made up of 27 bones that fall into 3 areas which are the carpals, metacarpals and phalanges.
There are 8 Carpals, Trapezium, Trapezoid, Capitate, Hamate, Scaphoid, Lunate, Triquetrum and the Pisiform.
There are 5 Metacarpals, the 5 Metacarpals that form the palm of the hand.
There are 14 Phalanges, they form the fingers. Each finger has a proximal, middle and distal phalange. The thumb has only 2 phalanges.
The muscles in the hands and feet are skeletal muscles and they are in charge of the movement of the hands and fingers. …show more content…

The bones of the foot are made up of 3 arches
The Medial arch runs down the medial length side of the foot and consists of the calcaneus, navicular and all 3 cuneiforms.
The Longitudinal arch runs down the lateral length of the foot and consists of the calcaneus, cuboid and the lateral metatarsals.
The transverse arch runs across the foot and is formed by the cuboid, 3 cuneiforms and the base of the five metatarsal.
The muscles of the lower leg and foot can be divided into the interior, posterior and lateral compartments.
The anterior muscles of the lower leg dorisflex the ankle joint and extend the toes. These are the Tabialis anterior, The Extensor hallucis longus, The Extensor digitorum and the peroneus tertius.
The Posterior muscles plantar flex the foot and flex the toes. These are
Gastrocnemius, Soleus, Flexor Hallucis Longus, Flexor digitorum longus and the Tibialis posterior.

The lateral muscles, plantar flex the ankle joint and everts the foot; these are Peroneus longus and Peroneus brevis.
Muscles of the dorsum of the foot extend the toes. The Extensor digitorum brevis extend toes 2-4 while the Extensor hallucis brevis extends the big

Lying sideways with the injured leg straightened on the floor, he should cross the uninjured leg in front of the injured one. This will force the injured leg to extend and bear weight. The gluteus maximus’ action is extension, external rotation, and hip abduction. The origin is at the ilium, sacrum, and coccyx, the insertion is at the lateral surface of the greater trochanter, and it is innervated by the inferior gluteal nerve. Lying on the side of the uninjured leg

Chapter six welcomes us into the skeletal system by presenting functions,types,structure, and development of bones. We are also presented the ideas of fractures and even the spine- curling snap of a broken bone which means a band aid simply won 't do! For example, Hematoma formation , Fibrocartilaginous callus, Bony callus ,and Remolding must occur to heal ,aka 3-10 weeks in a signature infested cast ,and if the break eventuated* on your arm, a complementary farmer 's tan. The Axial Skeleton makes an appearance by explaining itself as lying in the middle of the body and consisting of the skull, hyoid bone, vertebral column, thoracic cage, and middle ear bones. The complexity, physiology and delicate fashions of each member of this group is expressed.

Many people may assume that bones are all the same. However, bones can be classified by shape, structure, and bone markings. Bones are categorized as sutural, irregular, short, flat, long, and sesamoid bones based on their shape (Martini et al. 180). The long bones contain a diaphysis, epiphysis and metaphysis. The diaphysis in the long bone is made of compact bone which has a medullary cavity where marrow is kept.

Understanding the tibiofibular syndesmosis needs a hint of the surrounding anatomic structures. Talocrural and Subtalar Joints The ankle, or talocrural joint, is a modified-hinge, uniaxial joint formed by the medial malleolus of the tibia, the talus and the lateral malleolus of the fibula. Specifically, the convex superior articular surface of the talus or trochlea articulates with the concave distal articular facet of the tibia. The medial malleolus articulates with the medial aspect of the trochlea whereas the lateral malleolus articulates with the lateral aspect of the trochlea.

Small buds appeared and genes like sonic hedgehog shaped them into fins. Over millions of year’s fins evolved into a myriad of forms… as millions of years past, more variations. From clawed limbs of reptiles… to the powerful arms of primates that could traverse through the trees, until eventually a remarkable piece of anatomy arose that would itself transform the world. The human hand. This history is not just in our bones, flesh and muscle it’s in our DNA and that’s what connects us to our inner fish” (Shubin, Your Inner Fish,

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.

Radiological anatomy of the Wrist Osseous Anatomy The osseous structures of the wrist are the distal portions of the radius and ulna, the proximal and distal rows of carpal bones, and the bases of the metacarpals (Fig. 1). The proximal row of carpal bones consists of the scaphoid, lunate, triquetrum, and the pisiform. The distal row of carpal bones contains the trapezium, trapezoid, capitate, and hamate bones. The distal row of bones articulates with the metacarpal bases.

The carpal tunnel functions as an entrance to the palm for many tendons and median nerve (1). The median nerve is one of the five branches that make up the brachial plexus. This nerve provides motor innervation to the flexor muscles of the forearm and hand as well as muscles responsible for movements of the thumb. It also provides sensory innervation to the volar aspects of the first three digits and half of the fourth digit, the palm, and the medial region of the forearm (2). Carpal tunnel syndrome (CTS) is a common painful disorder of the wrist and hand.

In short stories, authors tend to create a suspicious mood by leaving out some information and making themselves seem unreliable. The use of dramatic irony by authors is purposeful to make them seem like unreliable narrators and lead to the reader questioning the outcome of the story. This is highly prevalent in the short story, “The Cask of Amontillado” by Edgar Allen Poe. The story takes place in Italy, amid the carnival, and tells the story of Montresor, who looks for revenge on Fortunato, an individual aristocrat who has caused harm to him before. Montresor then lures him into the catacomb and murders him.

The gastrocnemius muscle of the frog was dissected away from the tibio-fibula bone while still being attached to the knee. The other parts such as the foot, thigh muscles and others were removed from the tibio-fibula except for the sciatic nerve and gastrocnemius. Bone shears was used to cut the tibio-fibula bond 8-10mm below the knee. The femur was cut close to the hip joint. The muscle left in the petri dish was moistened using the Frog Ringer’s until ready to

Plastron – *The plastron or ventral shield is composed of nine bony pieces, of which eight are paired. * The anterior pairs of bones are the episternals, the middle pairs are the hyosternals and hyposternals, and the hinder pairs are the xiphisternals. The unpaired piece is called entosternal. *

Sixty to sixty five percent populations have loops, thirty to thirty five percent has whorls, and about five percent are arches. These three classes form the basis for all the ten-finger classification systems presently in use. i. Arch: In arches the ridges of the finger run from one side to the other with no re-curving. There are two sub groups

The neutral foot arch is your normal arch wherein half of your arch touches the ground. Your heel, ball of the foot and your big toe have just the right arch alignment. As such, having a neutral foot arch is considered to be the most efficient type of foot because of its good structure and ability to absorb shocks properly. Though having a neutral arch is the most efficient, it doesn’t mean that you won’t be at risk of developing foot problems. Low foot arch.
