Humerus

muscles and bones primarily in the arms. A few of the bones that we use are phalanges (In the hand), carpols, metacarpols, radius, ulna, and the humerus. You use your phalanges and metacarpols to grip the ball and your carpol to flick it away from you. while throwing the ball, both flexion and extension occur, which is where you move the ulna, radius, and humerus. The muscles you must use when doing a throw-in include triceps branchii, biceps branchii, and deltoid. These muscles allow you to…

There is bone checking on cervical, thoracic, vertebrae. These bones are irregular, so they gathered by cervical, thoracic, lumbar, and sacral. The gatherings have different measures of vertebras for everyone. The cervical spine aggregate has seven vertebras. The thoracic spine aggregate has twelve. There are five vertebrae's in the lumbar spine. The last section is sacrum, and there is five vertebrae's in the sacrum excluding the three vertebrae's in the coccyx. "Bone markings along the edge of…

Name: Muhammad Rahim 17/09/2015 1.1 Skeletal Systems P1 Describe the structure and function of the skeletal system. In the following diagram on the right, The Axial Skeleton is shown in red and the Appendicular skeleton is shown in blue respectively. Five Different Types of Bones According to the shapes of the bones and their structure, bones can be classified accordingly. The main 5 types of bones (in terms of their shape) are listed together with brief descriptions and examples of…

P1 the structure and function of the skeletal system The structure of the skeletal system is very diverse and complex, made up of many different components that all work together to perform certain functions, without these individual components the whole body would fail to work efficiently when attempting to preform even the easiest of tasks. Structure of skeletal system One vital section is the axial skeleton this is the component of the skeleton that consists of the bones of the head and…

Summarization: Terrestriality was suggested to have been more common in the past than it is today, according to primate fossil records obtained from many museums around the country. This terrestriality is more prominent amongst cercopithecoid primates. Preference of habitually terrestrial substrates was based on primate forelimb anatomy. Extant large-bodied terrestrial…

In particular, the infraspinatus is involved in external rotation and stabilization of the humerus as a humeral head depressor by pulling the humerus towards the glenoid fossa of the scapula (Ngomo, Mercier, & Roy, 2013). There was an increase in superior translation of the humeral head while using a nerve block to cause dysfunction of the infraspinatus and supraspinatus…

effect of another underlying cause taking place in your body. Osteolysis tends to be idiopathic which means it came about spontaneously and the cause is undiscovered. The first case of Osteolysis was reported in 1838 in which an 18 year old man’s humerus disappeared completely. It disappeared over a course of 11 years, in which he suffered two fractures to the bone. The man was still able to perform life sustaining activities up until his death at age 70. The Gorham-Stout syndrome acts as a…

designed? - The elbow, in essence, is a joint which is formed by the union of three major bones is supported by ligaments. Connected to the bones by tendons, muscles move those bones in several ways. The bones that create the elbow are included:  Humerus: This long bone extends from the shoulder socket and joins the radius and ulna to form the elbow.  Radius: This forearm bone runs from the elbow to the thumb side of the wrist.  Ulna: This forearm bone will run from the elbow to the…

provides a great example are frogs, birds, rabbits, and lizards. “Frogs, birds, rabbits and lizards all have different forelimbs, reflecting their different lifestyles” (“Homologies”). “But those different forelimbs all share the same set of bones - the humerus, the radius, and the ulna” (“Homologies”). “These are the same bones seen in fossils of the extinct transitional animal, the Eusthenopteron” (“Homologies”). This shows common ancestry between these common day mammals and prehistoric, now…

Scapula: The scapula attaches the upper arm to the thorax. This stabilizes the arm and allows the shoulder to move around with ease. Humerus: The humerus connects the shoulder with the elbow, it allows the lower part of the arm to move in a wide range of directions without any difficulty. Ulna: The ulna is attached to many muscles in the arm to perform movements of the arm, hand and wrist. The…
