Humerus

The teres minor, infraspinatus, supraspinatus, and the subscapularis all are attached to the humerus via their tendons. These tendons are fused together to form the cuff, that in turn, allow for the movement of the shoulder to play sports and do the daily activities that most of us take for granted such as comb our hair. Athletes such as baseball…

Triceps Brachii Long head: infraglenoid tubercle of scapula; Lateral head: posterolateral humerus and lateral intermuscular septum; Medial head: posteromedial surface of the inferior half of humerus. Ulna olecranon process. Extension of the forearm and long head. Deltoids Lateral 1/3 of the clavicle, acromion, and the lower lip of the crest from the spine of the scapula. There is deltoid tuberosity of the humerus bone. Arm abduction; flexibility of anterior fibers and rotation of the arm…

assists in the formation of certain cavities in the head along with fossae in chickens. In humans, the humerus serves as a insertion and origination point for numerous muscles, such as the pectoralis major and the deltoid. Its primary function is the facilitation of movement and support for the arm . In chickens, the humerus, along with the coracoid and scapula, forms the shoulder. The humerus also joins the radius and ulna to form the elbow. These allow for movement of the arm and are extremely…

To be a baseball catcher it is very important you have the right setup of their body in back of the plate. Baseball catchers have to go through a lot of strength training and drills to gain that ability to have the right stance and be able to keep that position and be able to change positions when needed. It looks like a very easy position but in the end it is one of the most important positions in baseball. To start off in the position you will have cervical extension to be able to watch what…

The human shoulder is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons. The rotator cuff is a group of muscles and their tendons that act to stabilize the shoulder. The four muscles of the rotator cuff are over half of the seven scapulohumeral muscles. The four muscles are the supraspinatus muscle, the infraspinatus muscle, teres minor muscle, and the subscapularis muscle. The…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

deepens the cavity of the Glenoid. The labrum allows for full range of motion, stability, and cushioning in the shoulder. It is attached to the edge of the shoulder socket and supports the ball of the joint -or the head of the arm bone, known as the humerus- in order to stay in place. When the fibrocartilage of the labrum is torn, it is considered a labral tear. There are three common labral tears; Posterior labral tears, Superior labral tear from anterior to posterior (SLAP tear), and Bankart…

anteromedial and anterolateral surface of the middle third of humerus ,embracing the deltoid insertion. In addition it also had attachement to the adjoining part of the lateral intermuscular septum. Its fibers ran vertically and terminated in a thick tendon to be inserted onto the ulnar tuberosity. Fibers of the deep head could be seen arising from the anterormedial and anterorlateral suaface of the distal third of the humerus. In addition fibers were seen to be attached…

Jason Ramdat, Lab Essay #2, Lab Code 1B, 12/8/14 Vertebrates’ forelimbs are anterior appendages of animals that are in the subphylum vertebrata. There are several bones that makes up a forelimb includes the radius, ulna, humerus, carpal, metacarpals, and phalanges. The humerus is a single heavy bone which articulates with the body and forms the foundation of the limb; the radius and ulna are lighter and provides support in addition to a greater range of movement (AMNH Plaque). The carpals,…

Gender was the longest test done. I measured the pelvis, skull, tibia and humerus. The results were astonishing. I used a female and male pelvis pictures, vernier calipers, tape measure, a ruler, and protractor to find the angles and or lengths of parts of the bones. I measured the sub-pubic angle first and it came out to be 90…
