Upper limb

contrast, the jerboa lives in a terrestrial environment. The jerboa is bipedal, and moves using solely the back legs; the forelimbs are used for collecting food and digging. The jerboa uses jumping as its locomotion style. The hind limbs have a short forelimb and a long hind limb. The jerboa’s hind leg design results in a large gear ratio, and therefore is designed for…

childhood which primarily affects boys characterized by progressive muscle weakness and wasting due to a mutation in the dystrophin gene of X chromosome. Degeneration of muscles usually begins to appear in the lower half of the body then spreading into upper limbs and eventually leading to death. Between 1830 and 1850 scientists reported on an illness where boys grew gradually weaker, lost the ability to walk and died at an early age. A decade later, French neurologist Guillaume Duchene first…

neurons. Motor neurons are nerve cells that are to be located in the brain, brainstem, and spinal cord that are the controlling unit and vital communication that links between the nervous system and voluntary ,muscles of the body. In ALS the upper motor and the lower motor die and stop sending signals or messages to the muscle,now that the muscles are unable…

Life without limbs: Acceptance, Positive perspectives and Social Support Bianca Dia S. Duran Juli-ann L. Alonso - Balmonte Limb loss or Limb amputation is a type of physical disability that is defined as surgically the complete removal, or spontaneous partial removal of a body part. It is constrained to perform an activity independently such as walking, bathing, toileting, etc. A famous example of persons without limbs is Nick Vujicic a motivational speaker, has a rare disorder with an absence…

africanus greatly influenced their diet. While their limb proportions suggest a forsested environment, the evidence of bipedality in their skeletal features supports the idea of there being a savanna to thrive in as well. A. africanus is estimated to have existed in southern africa 3.2 to 2 million years…

girdles as well as their attached limbs associated with skeleton models found in your text. The pectoral griddle contains: 2 clavicle bones (known as collarbones that brace the scapula and arms making up the shoulder); and 2 scapula bones (known as the shoulder blades functioning as a stabilizer and provides movement of the shoulder). The attachments of the upper extremity from the pectoral area includes: 2 humerus (these are the largest and longest bones in the upper extremity articulating with…

included skin and subcutaneous tissue infections (43.2%), open wounds of extremities (22.1%), and open wounds of the head, neck, and trunk (10.5%). Other chief diagnoses included fracture of upper limb, infective arthritis and osteomyelitis, septicemia, crushing injury or internal injury and fracture of lower limb.6 When the attack stems from a dog owned by a family member, even…

the sacrotuberous ligament. There is also attachment to fascia overlying the gluteal medius muscle and between the ilium and sacrum, to fascia covering the erector spinae muscle. It covers diagonally downwards and laterally towards the femur. The upper two thirds and superficial lower part of the muscle radiate more laterally and insert into the posterior aspect of a tendinous thickening of the fascia lata (the iliotibial tract). Fascia lata later inserts laterally at the tibia and fibula.…

The striatum projects to and inhibits the GPi which has tonic inhibitory connections to the VA/VL nuclei of the thalamus and finally back to the motor and premotor cortex.1 Activation of the direct pathway initiates voluntary movement, by releasing upper motor neurons in the cortex from inhibition.1,2 The globus pallidus, internal and…

engine that keeps a super-powered locomotive speeding around the planet, the depleted lower classes lived-in the rear cars (Curtis, Edgar, Gilliam, and many others) while the privileged upper classes are indulged in the front( Mason and Wilford along with others). The balance of power between the lower and upper classes begins to shift, however, when an enigmatic message sparks a revolt that cannot be quelled. When I was watching this movie…
