Essays on Humerus

The aim of this essay is the presentation of 30 human bones associated with the skull, the vertebral column, the thoracic cage, the pectoral girdle and upper limb, the pelvic girdle and lower limb, and the joints. The review will be conducted in categories and will include a description of the function and their classification. The bones of the skull can be divided into two categories: the cranial bones (the calvarium and the cranial base) and the facial bones. Three bones of the calvarium are the frontal bone, the occipital bone, and the parietal bone. The frontal bone forms ...

The requirements to be filled on a patients admission form after an open reduction and internal fixation will include; the patient’s full name, the date of birth, weight, height, and vitals (such as; health status), the M/S on the bone status which will include; fractured right femur and humerus, muscle strength, extensor, abductor muscle strength, normal fixed supinated cavus type foot, the heartbeat rate and rhythm, and the capillary filling. This information will be vital in determining if K.B. needs to undergo surgery, hence cold pack is preferred as it will ease any pain and swelling. It will ...

The Rotator Cuff - Overview

As defined in the article “Rotator Cuff Injury and Inflammation” the rotator cuff is in the shoulder joint, and comprises four muscles called: Supraspinatus, Infraspinatus, Subscapularis, and Teres minor respectively. They are illustrated in Figure 1 below, reproduced from the same article: (Reproduced from “Rotator Cuff Injury and Inflammation”) As described in the referenced article, these muscles function together to help the movement of the shoulder joint and stabilise it.

Causes, Symptoms, and Prevention of Rotator Cuff Injuries

According to Wedro and Stöppler (Ed.) in their article “Rotator Cuff Disorders” (n.d.), the usual cause of a problem ...

For a long time, Australopithecus afarensis was considered as the earliest known bipedal hominid. This made this species, which was dated to have existed around 3.5 million years ago, the oldest member of the human clan. However, the discovery of the species, Australopithecus anamensis pushed the age of the bipedal hominids further back by around 600000 years (Tomasik, 2002).

History of the Discovery of Australopithecus anamensis

In 1965, the first fossilized specimen of A. anamensis was discovered by a research team from the Harvard University in the Kanapoi region that lies on the west of Lake Turkana in Kenya. Although at that time the fossil, which was a humerus ...

Part one

Once the thirst hub situated in the lateral hypothalamus informs the body of dehydration, it will react by stimulating drinking behavior. The brain sends sensory messages to appropriate muscles to lift the glass of water for drinking purposes. Impulses arise from the cerebral motor compound of the brain. The impulses then move via the corticospinal tract1, which traverses via the midbrain, the pons and the medulla until it departs from the skull via the occipital foramen and goes into the spinal cord. From the spinal cord, the impulse journeys through explicit nerves that branch outwardly on the spinal column ...
