The human skeleton performs many functions in the human body. It supports the body and covers soft internal organs which would otherwise get easily damaged. It provides locomotion, even though muscle contractions are needed for movement, bones are what actually moves the body in various ways and are attached to skeletal muscle. The skeleton helps a human being run, walk, swim, etc. The skeleton also takes part in the production…
Colobus Guereza Suborder: Halporhini Superfamily: Cercopithecidae Family: Colobinae Colobus Guereza, or the Mantled Guereza, is a member of the Colobinae family, which contains Old World, leaf-eating monkeys. We chose the species for a couple reasons. First, its mantle of white long, white hair, which is distinct and the source of its name. Second, it is one of the only Colobinae species present in US zoos. The Mantled Guereza is endemic to Equitorial Africa. It can be found in forests,…
CHARACTERS OF PRIMATES Introduction – The members of the order primate are characterized by having forward-facing eyes and very flexible fingers, legs and arms that assist them to lead an arboreal life which arefound allover the world. They have large brain in comparison to other mammals. They show a combination of primitive and specialized characters. They are primarily arboreal and return to land as a secondary condition…
Planarians are triploblastic acoelomates, meaning they have three tissue layers, ectoderm, mesoderm, and endoderm (Newmark and Alvarado, 2001). Their epidermal layer that surrounds the planarian is ciliated on the ventral surface (Newmark and Alvarado, 2001). Underneath the epidermal layer and the basal lamina, followed by a complex wall musculature that surrounds the body. The complex wall muscle is composed of the circular diagonal and muscle fibers (Newmark and Alvarado, 2001). The nervous…
along the body from segment 15 (where sperm ducts are also located) to the clitellum, which looks like a tube surrounding the earthworm’s body and is closer to the anterior end. 4. The setae are likely on the outside of the body for more effective locomotion. They allow the earthworm to grasp onto the soil as its muscles contract, moving it forward. The setae’s grip also prevents predators from snatching the earthworm off the ground. If the setae were located on the inside of the body, the…
With increasing populations the number and proportion of older Australians are also expected to increase. Stroke is identified as a frequent cause of disability amongst adults as in 2009, 375800 Australians experienced a stroke with 70% aged over 65 (Australian Institute of Health and Welfare [AIHW], 2013, p 15; Wist, Clivaz, & Sattelmayer, 2016). It is likely as the ageing population increases, so will the number of stroke cases (Wist, et al., 2016). There are two types of cerebrovascular…
Ophiothrix spiculata (a.k.a. spiny brittle stars) are the most diverse organisms in phylum Echinodermata that can be found in the ocean all over the world. They are spotted in many different colors such as orange, yellow, red, blue, black, or even tanned with reddish and white bands on their arms. Most spiny brittle stars have either round or star-shape body that are usually not larger than three centimeters. The body is called the central disk which consists of the dorsal shield (aboral side)…
females, a male takes over a group of another male or bi-male group. A dominate male breeds frequently and defends the group. The olive colobus communicate by a very quite chirping and burring calls. They also move threw the forest quadrupedal locomotion to keep away from predators. Their greenish coloring for kits pelage helps camouflage them also from predators. The olives colobus monkey is an accomplished leapers, to also avoid predators. They are know for sharing habitat with the Diana…
Introduction: Drosophila melanogaster is the common fruit fly which spends a majority of its time accumulating around spoiled fruit and vegetables. They are one of the most studied organisms in biological and genetic research. One of the primary reasons they were chosen as a model organism due to their fast breeding rate and easy manipulation control. The lifespan of the Drosophila is approximately 12-30 days at 29 °C (84 °F) . The development of the Drosophila takes place with a fertilized egg…
To fully understand this Grip Strength exercise there most be an understanding of the foundational physiological mechanisms, which are involved. These mechanisms are all incorporated into the muscular system of the body and its foundational unit known as muscle. A muscle can be defined as a bundle of fibrous tissue connected to two or more bones by tendons giving it the ability to contract and therefore inducing movement to a specific part of the body. The muscles within the human body are…
