Chapter 32 – An Introduction to Animal Diversity All animals share a common ancestor‚ sponges are basal animals‚ eumetazoa is a clade of animals with true tissues‚ most animal phyla belong to the clade bilateria‚ and vertebrates and some other phyla belong Animals share a unique homeobox-containing family of genes‚ known as the Hox genes‚ suggesting that this gene family evolved in the eukaryote lineage that gave rise to animals. Hox genes play important roles in the development of animal embryos

Mammary glands: feature for which mammals are named-produce milk to nourish the young. Having hair‚ ability to nourish their young with milk‚ all breathe air‚ have four chambered hearts‚ and are endotherms. The first true mammals appeared during the late Triassic period‚ about 220 million years ago. Mammals are descended from ancient reptiles. * * Form and Function in Mammals * * Body Temperature Control * High metabolic rate‚ helps generate body heat. External body hair

Word Count: 2481 Abstract Convergent lines of evidence indicate that introducing a physically warm stimulus‚ such as a heat pack‚ results in individuals interpreting a target person as “warmer”. Neurobiological mechanisms responsible for thermoregulation may be shared by mechanisms responsible for interpretation of interpersonal warmth‚ and may be connected to sympathetic nervous system activity. To test this‚ we attempted to replicate findings from Williams and Bargh (2008) that found a significant

water by osmosis. In the case of lactose intolerance‚ when lactose is ingested it will not be broken down and continues along the gut‚ thus causing water to be pulled out of the cells and liquefying the stools (diarrhoea). Water is important in thermoregulation. When the thermoreceptors perceive an increase in temperature‚ a signal is sent to the heat loss centre in the hypothalamus which starts the heat loss mechanism such as vasodilatation‚ lowering of body hair‚ and sweating or pantinh. Sweating

Dreaming When’s the last time you dreamed? In fact‚ the last time sleep occurred is the correct answer. Most people believe that they don’t dream‚ only because these individuals can’t recall dreaming as an event. In J. Allan Hobson’s book‚ Dreaming‚ it explores how dreaming is influenced and how it affects the individual‚ how dreaming is associated with REM (Rapid Eye Movement) sleep and the importance of it‚ and also why sleep is so essential for human beings and other mammals to experience. Sleep

Thermoreceptors are specific nerve cells that are able to detect differences in temperature. Thermoreceptors are able to detect heat and cold‚ and are found throughout the skin in order to allow sensory reception throughout the body. The body’s core temperature is a constant 37° C by physiological adjustments controlled by the hypothalamus where there are neurons sensitive to changes in skin and blood temperatures. The temperature-regulating centres are found in the Preoptic Area. This area receives

A. cerebrum- constitutes about 83% of its volume and consists of a pair of half-globes called the cerebral hemispheres. B. cerebellum- lies inferior to the cerebrum and occupies the posterior cranial fossa. C. brainstem- that which remains of the brain if the cerebrum and cerebellum are removed. 2. Gyrus- a wrinkle or fold in the cortex of the cerebrum or cerebellum. Sulcus- a groove in the surface of

Some researchers reported that CXB melting point ranging from 160.79–164.64°C (127)‚ and Paradkar A. et al. (2002) reported that sharp endotherm corresponding to its melting point at 163.3°C (128). The thermal behavior of CXB‚ soluplus‚ corresponding PM and their SDs at three different ratios were evaluated by DSC in Figure (10). The thermogram for Soluplus showed broad endothermic peak
