Humerus Essays

adults, the elbow is the second most dislocated joint in the body, succeeding shoulder dislocations. Most elbow dislocations occur in the posterior direction, which causes a disengagement of the “coronoid process of the ulna from the trochlea of the humerus” (Chicharoen, Kwon, Windle, & Lovato, 2014). Typically, the mechanism of injury is falling on an outstretched hand (FOOSH) with the elbow in an extended position upon impact. For example, an athlete participating in the first practices for two-a-day

Hockey is more dangerous and intense than football Hockey is ranked 9th in most popular and challenging sports but football is not seen in the ranking. Hockey is more challenging and more physical than football, which is why its ranked 9th. Though football has many head injuries hockey has many other injuries involved with it as well. Playing hockey takes lots of skill, intensity, and its more physical. First, Hockey is more dangerous than football because of the injuries. In hockey injuries

Everyone loves to live an active life & indulging in some sort of sports gives one a good opportunity to have an energetic life. Obviously, sports like basketball, volleyball, indoor soccer are fun to play & also builds character. However, one of the most important aspect while playing these, or for that matter any other game is safety. If you are into sports, safety is a priority for you. Injuries are common in sports, but what if you get injured due to bad quality surface. Well, if one gets injured

A third injury is called frozen shoulder this is also known as adhesive capsulitis. Frozen shoulder is in the area that is called the shoulder capsule, strong connective tissue that surrounds the joint. The shoulder capsule becomes tight in the shoulder and stiffens the bands of the tissue. There may be less synovial fluid in the joint. This condition limits your range of motion and can scar tissue overtime as it develops. There's not enough space to actually rotate your joint properly and this frozen

Shoulder Impingement Syndrome With Rehab Shoulder impingement syndrome occurs when certain cords of tissue (tendons) under the bone (acromion) at the top of the shoulder blade become pinched. These tendons are part of the group of muscles and tissues that help to stabilize the shoulder (rotator cuff). Beneath the rotator cuff is a fluid-filled sac (bursa) that allows the muscles and tendons to glide smoothly. This sac may become swollen or irritated (bursitis). Bursitis, swelling in the rotator

lateral epicondyle of the humerus and the insertion is the lateral surface of the radius (Shier, 2007). The extensor carpi ulnaris, extensor carpi radialis longus and brevis, and extensor digitorum extend the hand, unclenching the fist (Shier, 2007). The extensor carpi radialis longus originates at the distal end of the humerus and inserts at the base of the second metacarpal (Shier, 2007). The origin of the extensor carpi radialis brevis is at the lateral epicondyle of the humerus (Shier, 2007). The insertion

at the lesser tubercle of the humerus. Its function is to medially rotate the shoulder at the G/H joint and stabilize the head of the humerus in the G/H joint while helping protect and stabilize the head of the humerus in the G/H joint. The supraspinatus originates at the supraspinatus fossa of the scapula and inserts at the greater tubercle of the humerus. Its function is to assists the deltoid abduct the arm while helping protect and stabilize the head of the humerus in the G/H joint. The infraspinatus

Brachioradialis a. The brachioradioalis originates onto the lateral supracondylar ridge of the humerus, and inserts onto the styloid process of the radius (Starkey, et al., 2011). b. Its main functions are elbow flexion, and pronation/supination of the forearm (Starkey, et al., 2011). Wrist Flexors 4. Pronator teres a. The pronator teres originates on the medial epicondyle of the humerus, and the coronoid process of the ulna. Both these origin points inert onto the middle one third of the

The specific anatomical location of her fracture is, the proximal area of the humerus. The specific type of fracture that Mrs. Smith suffered is a closed (simple) fracture. Now that we know the specific details of her fracture, let’s get into what organ systems that could be impacted by her fracture. Based on the details we know about

Shoulder Dislocation A shoulder dislocation happens when the upper arm bone (humerus) moves out of the shoulder joint. The shoulder joint is the part of the shoulder where the humerus, shoulder blade, and collar bone meet. CAUSES This condition is often caused by: A fall. A hit to the shoulder. A forceful movement of the shoulder. RISK FACTORS This condition is more likely to develop in people who play sports. SYMPTOMS Symptoms of this condition include: Deformity of the

The lower end of the humerus has two rounded knobs the lateral and medial condyles. Between the two of these is a hole that extends completely through the bone, this is called the supratrochlear foramen. The ulna and radius act as one bone and are held together firmly by ligaments and always move together. The upper end of the ulna has a hook like process that fits perfectly in the supratrochlear foramen of the humerus. On the ulna there is a ridge called the trochlear

department to examine skeletal remains and figure out it’s gender, ethnicity, age, and height by using it’s bone measurements. Summary of Findings: Determining the sex: To determine the sex, we took measurements of the pelvis, skull, femur, and humerus. The results for the pelvis were both equally male and female. The pubis body width was 25mm, which fits into the ‘Male’ category along with the Sub-Pubic Angle being lesser than 90 degrees. The pelvic cavity shape (circular) and greater sciatic notch

most used joint besides knees are probably elbows. The elbow joint is primarily used to help position, and rotate the the arms, and hand. With that, primarily over the years the wear and tear of the ligaments, and bone structure of the three bones (Humerus, Radial, and Ulna) can lead to Osteoarthritis. Osteoarthritis is a degenerative joint disease that is caused from the ages around fiftey.. The wear and tear part comes in when the cartilage that houses the joint wears away; the bones are then exposed

Dislocation is the term given to the displacement of bones from their normal position, considerable force is needed to do this. The elbow joint is a complex synovial hinge – where the ulnar, radius and humerus articulate. There are three types of dislocation, the range in severity. A simple dislocation is one in which no major bone injury has occurred. Fractures to the radial head and neck, olecranon and distal humeral condyles/epicondyles have been approximated to occur between 5% and 15% of all

Muscular dystrophy is known as a muscle disorder that is not associated with central nerve abnormality. Disease is supposed to attack the muscles that lack fiber in them. The stability of the sarcolemma muscles depends upon the two main elements, these are dystrophin and dystrophin associated glycoproteins. Pathophysiology of the disease has shown that the gene of dystrophin is present on the chromosome X around the locus p21. In addition to this, there are 3685 amino acids present in this muscle

severity of the rotator cuff treatments can vary as well. The tear may be a partial tear or a complete tear of the rotator cuff tendon called supraspinatus tendon. This tendon is located on the supraspinatus muscle and attached to the head of the humerus bone. This treatment would

Bone Detective Formal Report Sophia Dominguez Introduction:The skeletal remains of the victim was found in a park lying next to another set of remains. Only the skull, pelvis, humerus, and tibia were found. Summary of findings: In determining the sex of the victim, the pelvis was very circular and wide. Also, the sub-pubic angle was greater than 90 degrees, thus indicating she was a female.The ethnicity of the body is of african descent. When measuring the nasal spine, the results showed negroid

1. What is the mechanism of injury for a sternoclavicular sprain? In the majority of sternoclavicular sprains, what is the direction of clavicle displacement? The majority of injuries result from compression related to a direct blow, as when a supine individual is landed on by another participant, or more commonly, by indirect forces transmitted from a blow to the shoulder or a fall on an outstretched arm. The disruption typically drives the proximal clavicle superior, medial, and anterior.

Bone structure Spongy bone also knowns as cancellous contain red and yeallow bone marrow. Red bone marrow produces roughly 200 million of red blood cells (RBC) per a day. Yellow bone marrow contains primary fat cells. This can be transformed into red bone marrow to provide RBC if needed (Ivy Rose Holistic,n.d). The sponge is light and have low density which balance the heavier parts of bone. Sponge tend to form a long line of stress which gives strength and flexibility in that area (Biology dictionary
