Which branch of microscopic anatomy is the study of tissues? Histology Cytology Embryology Developmental anatomy Surgical anatomy \_\_\_\_\_\_\_ anatomy examines both superficial anatomic markings and internal body structures as they relate to the skin covering them. Regional Surface Radiographic Surgical Systemic The directional term that means \"in back of\" or \"toward the back surface\" is posterior. caudal. cephalic. anterior.

CO2 + H20 5 Н2 СОз The chemical reaction shown above has reactants COz and H2O, which are permanently consumed as H2 CO3 is produced. is an example of an irreversible reaction. can proceed to the right, where H2 CO3 is produced, or the left, where CO2 and H2O are produced. In the process of glycolysis two enzymes are involved in breaking glucose down to ten pyruvate molecules. six enzymes use two ATP to split glucose in half. ten enzymes are involved in breaking glucose down to two pyruvate molecules. Lactase is an enzyme that digests lactose. True False Glycolysis requires oxygen. True False The term \"metabolism\" refers to reactions involving the breakdown of complex molecules or the exchange of atoms between similarly sized reactants. reactions involving the breakdown of complex molecules into simpler ones. digestive system reactions that are either catabolic or exchange reactions. all the chemical reactions in the body. The building blocks that form the DNA double helix are called nucleotides. steroid bases. nitrogenous acids. Everything packaged by the Golgi apparatus for secretion leaves the cell within a vesicle. True False The term \"codon\" refers to a three-nucleotide sequence of DNA that codes for a protein. a three-base sequence of mRNA. the part of a RNA molecule where a new amino acid is added. an amino acid that is coded for by three bases of DNA. The amount of rough ER is greater in cells producing large amounts of protein for secretion. True False Which of the following choices describes three general functions cells must perform? Grow until dividing, store complex carbohydrates, generate antibodies Take up oxygen, prevent water entry, undergo mitosis frequently Maintain shape, obtain nutrients, and dispose of wastes Endocrine glands possess ducts to secrete their products into the bloodstream or into interstitial fluid. secrete mucus directly into a body cavity. lack ducts and secrete their products onto the skin surface. lack ducts and secrete their products into the bloodstream or into interstitial fluid. Endocrine glands secrete sweat. hormones. saliva. Another name for the skin is the \_\_\_ membrane. cutaneous parietal visceral mucous While most of the cells in a hair are dead, the living epithelial cells are found in the hyponychium. the cortex of the hair shaft. the hair bulb. the cuticle of the hair shaft. The function of melanin in the skin is to prevent infections. protect against UV light. help regulate body temperature. Sebum is a secretion that acts as a pheremone once reproductive maturity is reached. cools the skin and eliminates certain drugs. lubricates skin and helps defend against bacteria. From deep to superficial, the order of the strata of the epidermis is Basale - spinosum - granulosum - lucidum - corneum Corneum - granulosum - lucidum - spinosum - basale Corneum - lucidum - granulosum - spinosum -- basale Basale-granulosum -spinosum -lucidum - corneum Where does hematopoiesis occur? Nutrient foramina Endosteum Red bone marrow Yellow bone marrow Parathyroid hormone and calcitriol stimulate osteoclasts to resorb bone and release calcium into the blood. stimulate osteoblasts to deposit bone by producing calcified matrix. stimulate osteoblasts to resorb bone and lower blood calcium levels. Which hormone inhibits bone growth? Calcitonin Growth hormone Parathyroid hormone Thyroid hormone Bone is\_\_\_\_\_and contains mainly. highly vascularized; sensory highly vascularized; motor avascular; sensory Bone is considered an important storage reservoir for phosphate, glycogen, and nonpolar amino acids. calcium, phosphate, and lipids. steroids, proteins, and complex carbohydrates. calcium, complex carbohydrates, and polar amino acids.

Signal the bone to move. Sutures are joints that are found only where a facial bone articulates with a cranial bone. throughout the axial and appendicular skeletons. between certain bones of the skull. between all bones and teeth of the skull. The glenohumeral joint exhibits a low level of stability but a wide range of motion. a low level of stability and a narrow range of motion. The joint movement called eversion involves turning the palm of the hand laterally. turning the palm of the hand or sole of the foot laterally. turning the sole of the foot laterally. Which of the following describes a meniscus?

Acetylcholine exerts its effect by allowing calcium to enter the cell. binding to receptors at the motor end plate. activating acetylcholinesterase. Which of the following is not one of the rotator cuff muscles? Supraspinatus Teres major Conductive activity in a neuron generally causes it to secrete several types of neurotransmitters simultaneously, that are broadcast to excite and inhibit multiple targets. a specific neurotransmitter that either excites or inhibits its target. Which is not a function of the motor division of the nervous system? Transmits impulses to muscles and glands Conducts impulses from the CNS Voluntary control of skeletal muscle Transmits impulses from the viscera The portion of the nervous system that has voluntary control over skeletal muscles is the division. somatic sensory autonomic motor somatic motor The afferent division of the nervous system is also known as the division. ganglial sensory cranial efferent The glossy-white appearance of most axons is due to the white color of the perivascular feet. the covering of ependymal cells. their proximity to light-reflecting cartilage. the high lipid content of the myelin sheath. Match the cranial nerve number with its name.
