Anatomy and physiology of bones

Its insertion is at the pubis and linea alba via aponeurosisand its action is the compression of abdominal contents. The exception to this are the egg-laying monotremesthe platypus and the echidnas of Australia. The reproductive system has evolved for internal fertilization, with a copulatory organ present in most species.

The pancreas releases enzymes that aid in digestion so that nutrients can be broken down and pass through the intestinal mucosa into the blood and travel to the rest of the body. Blood contains nutrients and oxygen providing energy that allows the cells of the body to perform work.

It also sends a small slip of insertion to the 1st cuneiform. They lose water by panting rather than sweating.

It inserts into the posterior half of the lateral surface of the mandible.

Anatomy & Physiology

It is attached to the sustentaculum tali of the calcaneus and extends along the entire inferior surface of the navicular bone. These enzymes continue protein digestion and also provide carbohydrate and fat digestion. Part of the immune system that helps the body fight-off disease.

Digestion begins in the mouth where food is mixed with saliva to lubricate the food as it passes down the esophageus. Masseter[ edit ] The Masseter is a great, powerful, and very thick muscle covered by a tough, shining fascia lying ventral to the zygomatic archwhich is its origin.

The bony structures participating in this joint superiorly are the distal end of the tibia and its medial malleolus, and the distal fibula and its lateral malleolus. Xiphihumeralis[ edit ] The most posterior, flat, thin, and long strip of pectoral muscle is the xiphihumeralis.

The platysma covers the neck and allows the cat to stretch the skin over the pectoralis major and deltoid muscles. There are no teeth and the narrow jaws are adapted into a horn-covered beak. For example, cats clean themselves by licking their fur with their tongue, which causes them to swallow a lot of fur.

Its origins are ribs three—five, and its insertion is the coracoid process of the scapula. They face forwards in predators and sideways in ducks. Its action is to draw the scapula to the dorsal and caudal region.

Generally, students of certain biological sciencesparamedicsprosthetists and orthotists, physiotherapistsoccupational therapistsnursespodiatristsand medical students learn gross anatomy and microscopic anatomy from anatomical models, skeletons, textbooks, diagrams, photographs, lectures and tutorials, and in addition, medical students generally also learn gross anatomy through practical experience of dissection and inspection of cadavers.

Endocrine organs include the thyroid glands, parathyroid glands, adrenal glands and part of the pancreas. Deltoid[ edit ] The deltoid muscles lie just lateral to the trapezius musclesoriginating from several fibers spanning the clavicle and scapula, converging to insert at the humerus.

This is the most nutrient absorptive section of the small intestine. Anatomy and Physiology Course Description: Chyme is fluid that passes easily into the the small intestine, where the pancrease provides additional digestive enzymes.

The abdomen is composed of eleven segments, some of which may be fused and houses the digestiverespiratoryexcretory and reproductive systems. There is one living species, Sphenodon punctatus. Pectoralis minor[ edit ] The pectoralis minor muscle is larger than the pectoralis major.

Human anatomy can be taught regionally or systemically; that is, respectively, studying anatomy by bodily regions such as the head and chest, or studying by specific systems, such as the nervous or respiratory systems. Lizards have moveable eyelids, eardrums are present and some species have a central parietal eye.

They are tetrapodsbut the snakes and a few species of lizard either have no limbs or their limbs are much reduced in size. Mouth: Digestion begins in the mouth where food is mixed with saliva to lubricate the food as it passes down the esophageus.

Dog's teeth are suited for gripping, tearing and shredding the food.

Anatomy is a branch of natural science which deals with the structural organization of living things.

Cat anatomy

It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy. The anatomy of the domestic cat is similar to that of other members of the genus Felis.
