(ribs 1 to 8) while the insertion of this muscle is located on the costal surface of the medial border of the scapula. Therefore‚ this muscle is innervated by the long thoracic nerve which is a branch of the brachial plexus (ventral rami of C5‚6‚7) by virtue of the nerves anterior relation to the muscle. The long thoracic nerve runs over Serratus Anterior during its course on the medial wall of the axilla on the mid axillary line‚ after exiting through scalene muscle and passing over the first rib and

The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula is only involved to the extent that it serves as an attachment site for connective tissue. In this paper‚ the anatomy of the joint will be discussed. The knee is a hinge-type‚ diarthrotic‚ or freely moveable joint. Also referred to as a synovial joint‚ the 2 articulating ends of bone are encased in a capsule that lubricates the joint with synovial fluid to reduce friction

Mastication is the action of chewing on food using the teeth‚ making it easy to be ingested by the body. It is known to be the first and foremost step of digestion as food can’t be swallowed effectively without it being turned into something that is easily consumable. For the jaw to be able to churn the food repeatedly‚ it requires muscles to adduct and abduct as well as give it strength to bite on hard food such as tooth-crackers. Muscles of mastication are known to be the most crucial muscles

After this‚ it will be describing the characteristics of nerves‚ the different sections of the nervous system‚ and how nerves function in the human body. Then after that it will be describing the different nerves in the human body‚ like as mechanoreceptors‚ photoreceptors‚ thermoreceptors‚ and auditory receptors. Then after nerves‚ it will be describing to you the way anesthesia works in the body. First off by telling you the chemical compounds

The homeostatic capability of the body involves an internal balance in order for the body to properly function. This system is known as dual innervations. These are innervations affected by two systems known as the parasympathetic and sympathetic nerve systems. The effector organs for the sympathetic system include: the smooth muscle of blood vessels‚ lungs‚ viscera‚ scalp‚ pupils‚ the heart‚ and glands. The effector organs for the parasympathetic system include: lacrimal glands‚ salivary glands

From the repeated injuries Sannu is having repeated nerve damage. When someone has Leprosy and it is untreated they can lose sensation in that extremity due to the body’s defense mechanism. This will cause loss of feeling in the skin and weakens muscle. B. Leprosy can affect the skin and Schwann cells of peripheral nerves. Which events of sensation processing are most likely not functioning properly in Sannu’s leprosy? Generation of nerve impulses is probably not working properly. Sensory neurons
