Difference between Anatomy and Physiology is this that Anatomy is the study of structure while on the other hand Physiology is the study of Functions. Anatomy is the study of structure: Anatomy, which suggests "a cutting open" is the study of internal and external structures of the body and the physical relationships amongst body parts [...]
The law of complementary base pairing shows that we can forecast the base series of one DNA strand if we understand the series of the other. More notably, it allows a cell to reproduce one strand based upon info in the other. The essential actions of the replication process are as follows : The double [...]
There are more than 600 muscles in the body, but only a few of the major muscles are considered here. Muscles of Facial Expression And Mastication Muscles of the face and scalp produce the facial expressions that help communicate feelings, such as anger, sadness, happiness, fear, disgust, pain, and surprise. Most have origins on skull [...]
The colon reabsorbs salts and water. About 1500 mL of fluid enters the colon each day, but only 50 to 100 mL of fluid is excreted in feces. Anatomically, the colon is divided into the cecum, ascending colon, transverse colon, and descending colon. Segmental contraction of the circular smooth muscle divides the colon into numerous [...]
Teeth are important accessory digestive structures that mechanically break food into smaller pieces during mastication (mas-ti-ka'-shun), or chewing. Humans develop two sets of teeth: deciduous and permanent teeth. The deciduous teeth, the first set, start to erupt through the gums at about six months of age. Central incisor (in-si-zers) teeth come in first, and second [...]
Genetics is the study of heredity, the passing of inherited traits from one generation to the next. The determiners of hereditary traits are located on chromosomes, consisting of DNA and proteins. It is the DNA that controls inheritance and directs cellular functions. Each human body cell contains 46 chromosomes that exist as 23 unique pairs. [...]
Peroxisomes or microbodies are the membrane minimal vesicles like the lysosomes. Unlike lysosomes, peroxisomes are pinched off from endoplasmic reticulum and not from the Golgi apparatus Peroxisomes consist of some oxidative enzymes such as catalase, urate oxidase and D-amino acid oxidase. Oxidative enzymes, as the name suggests, utilize oxygen (02), in this case to [...]
Like loose connective tissues, dense connective tissues help binding tissues together and offering assistance fororgans Nevertheless, dense connective tissue has far less cells and ground substance and more various, thicker, and "denser" protein fibers. These tissues likewise include far less blood vessels than loose connective tissues There are 3 types of dense connective tissue: dense [...]
The anterior hypothalamic "thermostat" adjusts heat balance to maintain body core temperature. Heat exchange is determined by convection, conduction, evaporation, and radiation. Radiation, conduction, and convection are determined by the difference between the skin temperature and the environmental temperature. Behavioral mechanisms can assist thermoregulation. The rate of heat loss depends primarily on the surface temperature [...]
There are three basic types of blood vessels: arteries, capillaries, and veins. They form a closed system of tubes that carry blood from the heart to the tissue cells and back to the heart. Comparison of Arteries, Capillaries, And Veins Type of Vessel Function Structure Arteries Carry blood from the heart to the capillaries Control [...]
