Locomotion

In this lab, an experiment was done in order to test how the abiotic factor of temperature affects a Tenebrio molitor’s activity level. Both experiments conducted consisted of two separate treatment trials; one in a warm environment (25 C) and one in a relatively cold environment (14 C). Results obtained from these experiments both showed a higher level of T. molitor activity in warmer environments as opposed to the cold environment where less activity occurred. In this case, the activity level…

triploblastic, protostomes, and have bilateral symmetry. Mollusks have coelomate coelom, mesoderm lines the organs and body cavity. Phylum Mollusca has distinct features, such as a visceral mass, a muscular foot, and a mantle. The muscular foot aids them in locomotion and capturing food. In some cases, like class Cephalopoda, the foot evolved into tentacles. The mantle helps secrete the shell that some animals in certain classes have. In the class Bivalva, animals have two lateral shells…

Borneo and Sumatra. Their habitats include multiple tropical rainforests. There is an abundance of trees in the habitats of orangutans since they are highly arboreal animals, spending more than half their time in trees. Orangutans exhibit suspensory locomotion through using their exceptionally long arms to swing from branch to branch while moving through the trees. Their hands and feet are long and narrow with opposable thumbs and big toes, assisting…

changes. Because of these heat changes the shark can maintain itself for more than a month on a single large meal. Speed of locomotion plays an important role in an animal’s biology and ecology and is of particular interest in aquatic animals, especially in the white shark. In many animals, locomotion is the primary cause of energy expenditure. The average rate of locomotion is often correlated with metabolic rate which means the speed at which the shark moves through its environment…

Your subtopic, assigned to Paper Group 7, is “Adaptations in diving marine animals: cetaceans, pinnipeds, and penguins.” Birds and mammals have relatively high metabolic processes and require constant access to high quantities of oxygen for survival. If the brains of these animals are deprived of oxygen for even short periods of time, death may occur. Even though most humans can only hold their breaths for less than a minute, some marine air breathers have evolved strategies that allow them to…

Jason Ramdat, Lab Essay #2, Lab Code 1B, 12/8/14 Vertebrates’ forelimbs are anterior appendages of animals that are in the subphylum vertebrata. There are several bones that makes up a forelimb includes the radius, ulna, humerus, carpal, metacarpals, and phalanges. The humerus is a single heavy bone which articulates with the body and forms the foundation of the limb; the radius and ulna are lighter and provides support in addition to a greater range of movement (AMNH Plaque). The carpals,…

In the past, Walking or locomotion has been thought to be controlled by only the brain, and the spinal cord was merely a connector between the brain and the motor structure. The brain does control the voluntary muscle movement, but it works in conjunction with the spinal cord. It is now accepted that the motor patterns and rhythms governing locomotion in mammals are controlled by an area of the spinal cord known as the Central Pattern Generator (CPG) (Kiehn, 2006). The neural circuits in the CPG…

BASIC MORPHOLOGY A cartilaginous teleost This species of Triggerfish is seemingly unattractive. They are a highly compressed ovular species and are largely a dull gray color. A bright white line extends from its mouth to the anal fin dividing the darker gray above and the lighter gray below. The darker patterning on their body can be speckled, bars, or hardly visible. Their bottom jaw is exceptionally pale compared to the rest of their body and their eyes are set within a pale blue rim.…

I. INTRODUCTION HE versatility of muscles is a crucial factor for efficient animal locomotion. In combination with a high degree of force control muscles enable precise motions depending on the wanted action. Animal locomotion involves (a) fine motor skills like sneaking, grabbing and communication; (b) quick short term acceleration like catching prey; (c) very long-term movement patterns which need to be performed efficient like digesting, migration and sometimes even (d) avoiding motion by…

their physical, social, emotional and cognitive development (Marotz, 2012). Fundamental movement skills (FMS) are the building blocks for all movement (Landy & Burridge, 2002). FMS are commonly classified into three categories; non-locomotion (rolling, landing) locomotion (running, walking) and manipulation skills (hand-eye or foot-eye…
