Ulna

are made up a bone with a spherical head attached to a bone with a cup-like socket. This joint allows the most movement. (abduction, adduction, flexion, extension, and circumduction) -The elbow joint is a hinge joint that consists of the end of the ulna and radius and the end of the humerus. It allows flexion and extension movements and can only extend approximately 180 degrees. -Gliding joints (synovial joint) are usually a group of cube-shaped bones that can either move up and down, left and…

bone marrow. Diagram that includes the major parts -bones, ligaments, and tendon - and list the function(s) of each. NOTE: Your diagram should also include the following bones in the body: cranium, clavicle, humerus, scapula, sternum, rib, vertebra, ulna, radius, carpals, metacarpals, phalanges, pelvis (may list parts), femur, patella, tibia, fibula, tarsals, and metatarsals.Bones-The bone have very important nutrients, minerals, and fats and makes blood cells that are good for the body and…

hard place to live for a mammals but a dolphin are adapted for the marine environment. Inside their pectoral fins they have a skeletal structure similar to the human's arm and feet. Dolphins have a humerus, with a ball and socket joint. They have an ulna and radius and also as well as a complete hand structure, including the 5 phalanges. Dolphins and whales belong to the order Cetacea. Dolphins Are small toothed whales in a way.…

One of my mom’s best friends is Nikki, they’ve been friends since High School, so it’s easy to say that I’ve known Nikki all my life. Nikki at that time is married to Matt, and only had one daughter, Kylie. Nikki and Matt had only recently been married and moved into a new apartment not far from where my Mom and I lived. It was quite common that my mom and Nikki would take turns on who was babysitting, it was usually only for a couple of hours. One weekend in August 2004, Nikki and Matt…

iv. Increased enzymatic capacities for substrate catabolism v. Higher degree of clustering of subsarcolemmal mitochondria adjacent to capillaries-> higher O2 flux rates vi. Mitochondrial volume densities and surface areas per unit mitochondrial volume are near maximum theoretical limits in hummingbirds and higher than mammals-> achieved due to higher oxygen delivery capacities and substrate catabolism (Suarez et al. 1991) 5. Metabolic Substrate Turnover a. Questions i. Do hummingbirds…

1. The hypothalamus is the processing centre that controls the body temperature in the brain, through temperature receptors the skin is able to realize changes to external temperatures which send the information to the brain (hypothalamus). There are also temperature receptors that identify the temperature changes in the blood. The Processing centre triggers for the effectors (these are the sweat glands and muscles) to adapt in order the make sure our body temperature stays at 37°C. If we…

are perhaps the most common area of strain in musicians. First, a musician must understand that the wrist does not rotate. Any rotational movement should originate from the elbow and the distal end of the forearm, where the radius will cross over the ulna during pronation. Attempts to rotate the wrist itself can be problematic, so it is important for a musician to understand the structure and movement of these joints. Wrist injuries in musicians are common and are usually categorized as…

Triangular Fibrocartilage Complex (TFCC) is located on the ulnar side of the wrist. According to Barlow (2016), the TFCC contains an articular disc and three ligaments which attach to carpal bones, the ulna, and radius (p. 271). Blazar stated the three ligaments include the dorsal radio-ulnar ligament, the ulnar collateral ligament, and the ulno-carpal ligament (p. 60). The TFCC is a shock absorber, allows for wrist stability, grip, and weight bearing and rotational loading tasks. Neumann,…

This shows Onychonycteris finneyi, a bat fossil. The image shows its wing digits widely spread out with small claws on tip of each finger. It also shows the long tail found in earlier bat fossils (Moskowitz, 2008). Molecular Mechanisms The origins of bats wing muscles, molecular and cellular mechanisms are unknown but this research shows that the wing muscles of bats come from “a multiple myogenic source of different embryonic origins” (Tokita, Abe, && Suzuki, 2012). The results conclude that…

As M. tempus is an omnivore due to their monogastric digestive system, and is similar to a pigs digestive system, but with adaptations similar to that of bilbies (Thylacomyidae) due to the occasional low availability of prey and living food sources, resulting in adapted hindgut fermentation and a long digestive tract, (Tyndale-Biscoe C H 2005). Although M. tempus must ferment the consumed plant material, their gastrointestinal tracts are still incredibly different to those of foregut fermenters,…
