| Question | Answer |
|---|---|
| Which plane divides the body into left and right sides? a. Transverse b. Sagittal c. Frontal d. Coronal | b. Sagittal A sagittal plane is a vertical plane that runs from the front to the back, dividing the body into left and right sides. |
| The tibia is _______ to the femur. a. Proximal b. Distal c. Medial d. Lateral | b. Distal The tibia (shin bone) is further away from the trunk than the femur (thigh bone), so it is distal to the femur. |
| Which tissue has multinucleated striated cylindrical fibers and moves the body under voluntary control? a. Skeletal muscle b. Compact bone c. Cancellous bone d. Smooth muscle | a. Skeletal muscle Skeletal muscle has striated (long, thin, parallel streaks) multinucleated cylindrical fibers, and its action is under voluntary control (you consciously choose to move or activate them). These are the muscles attached to bones. |
| Which is the most abundant nervous tissue? a. Neurons b. Dendrites c. Neuroglia d. Myelin | c. Neuroglia The neuroglia, or glial cells, are the non-excitable nervous tissue. The glial cells are about five times more abundant than neurons. |
| Which of the following structure-function is incorrectly paired? a. Thymus—development of T lymphocyte b. Spleen—Filters blood c. Red bone marrow—Production of B lymphocyte d. Yellow bone marrow—Production of platelets | d. Yellow bone marrow—Production of platelets The yellow bone marrow does not produce platelets; instead, it stores fat. |
| Which type of bone has a diaphysis and two epiphyses? a. Irregular bone b. Long bone c. Flat bone d. Short bone | b. Long bone Long bones have a shaft (diaphysis) and two ends (epiphyses). Examples are the femur, the tibia, the fibula, the ulnar, the radius, and the humerus. |
| Which of the following is not found in the vertebral column? a. Coccyx b. Vomer c. Axis d. Atlas | b. Vomer The vomer is a small bone in the skull that separates the nasal cavity. |
| The pectoralis major pulls the arm towards the midline. This movement is called _________. a. Flexion b. Abduction c. Adduction d. Supination | c. Adduction The correct answer is Adduction. Adduction pulls towards the midline. |
| What is the role of calcium in muscle contraction? a. It binds to tropomyosin uncovers the active site of actin b. It binds to actin to initiate the formation of cross-bridges of myosin and actin c.It binds to troponin and to uncovers the active site | c. It binds to troponin and to uncovers the active site of actin Calcium binds to troponin and this causes tropomyosin to uncover the binding sites on the actin filament to which myosin can bind. |
| The nervous system is divided into two parts, namely ___________ and ____________. a. The central nervous system and spinal cord b. The central nervous system and peripheral nervous system c. The central nervous system and somatic nervous system d. Th | b. The central nervous system and peripheral nervous system The central nervous system and peripheral nervous system. The nervous system is divided into the central nervous system and the peripheral nervous system. |
| Which of the following glands is correctly paired with its hormone? a. Adrenal cortex-Epinephrine b. Pancreas-Glucagon c. Gonads-Follicle stimulating hormone d. Parathyroid gland-Thyroid hormone | b. Pancreas-Glucagon The pancreas is found in the abdomen. It consists of the exocrine pancreas and endocrine pancreas. The exocrine pancreas produces digestive enzymes. The endocrine pancreas produces hormones. |
| Which structure controls the activity of the endocrine system? a. Parathyroid gland b. Pituitary gland c. Hypothalamus d. Thyroid gland | c. Hypothalamus The hypothalamus is a structure in the brain that lies inferior to the thalamus. It is connected to the pituitary gland by a stalk. It acts as the control center for the endocrine system. |
| Where does erythropoiesis take place? a. Heart b. Yellow bone marrow c. Thymus d. Red bone marrow | d. Red bone marrow Erythropoiesis is the process of producing red blood cells. The red bone marrow produces red blood cells and the process of erythropoiesis is regulated by erythropoietin, a hormone produced by the kidney |
| The left atrium receives blood from the ______. a. Pulmonary vein b. Pulmonary artery c. Superior vena cava d. Inferior vena cava | a. Pulmonary vein The pulmonary veins carry oxygenated blood from the lungs to the left atrium. |
| What does the EKG do? a. Records mechanical activity of the heart b. Records interatrial pressure c. Records interventricular pressure d. Records electrical activity of the heart | d. Records electrical activity of the heart The EKG is the electrocardiogram. It records the electrical activity of the heart. |
| What is the function of the small intestine? a. Absorption of nutrients b. Mastication c. Propulsion of feces to the rectum d. Compaction of waste to feces | a. Absorption of nutrients The mucosa of the small intestine has finger-like projections called villi, and the mucosa is also thrown into folds called plicae circulares. |
| The bolus is formed in which part of the digestive system? a. Oral cavity b. Pharynx c. Stomach d. Esophagus | a. Oral cavity In the oral cavity, the teeth tear and grind food into small bits. Saliva moistens the food and the tongue helps to move the food and roll it into a bolus. |
| Which of the following correctly describes chyme? Partially digested food mixed with an intestinal secretion Partially digested food mixed with gastric juice Partially digested food mixed with saliva Partially digested food mixed with pancreatic se | Partially digested food mixed with gastric juice |
| Which structure transports urine from the kidney to the bladder? a. Ureter b. Prostate c. Urethra d. Collecting duct | a. Ureter The ureter conveys urine from the kidneys to the bladder. |
| What is the functional unit of the kidney? a. Ureter b. Nephron c. Glomerulus d. Tubules | b. Nephron |
| Which of the following correctly describes the function of luteinizing hormone? It stimulates the proliferative phase of the menstrual cycle in females It stimulates the maturation of the ovarian follicle in females It stimulates spermatogenesis in | It stimulates the production of testosterone in males The luteinizing hormone stimulates the Leydig cells to produce testosterone in males. In females, it stimulates ovulation. |
| Which of the following statements is incorrect about estrogen? It is produced by the cells of the ovarian follicle It stimulates ovulation It stimulates the proliferative phase of the menstrual cycle It is responsible for the female secondary sex c | It stimulates ovulation Estrogen is the sex hormone responsible for the female secondary sex characteristics |
| Which structure in the eye is responsible for color vision? Iris Cones Lens Rods | Cones The cones are photoreceptors found in the retina. They function in high light intensity and, as such, are for daytime and color vision. |
| Which of the following is a function of a neutrophil? Elimination of protozoa Initiating allergic response Phagocytosis of bacteria Production of antibodies | Phagocytosis of bacteria Neutrophils phagocytose and destroy bacteria and other pathogens. They are the most numerous white blood cells and are often the first cells to respond during an infection. |
| The specialized junction from which nerve impulses pass from one neuron to the next is called a _______________________. | Synapse The correct answer is Synapse. A synapse is a specialized junction between two nerves. Impulses can move from one nerve (presynaptic neuron) to another (postsynaptic neuron) |
