ANATOMY & PHYSIOLOGY TEST 6A What are male gametes called? sperm Leydig cells ________. secrete testosterone Which hypothalamic hormone contributes to the regulation of the male reproductive system? gonadotropin-releasing hormone What is the function of the epididymis? sperm maturation and storage Spermatogenesis takes place in the ________. seminiferous tubules Briefly explain why mature gametes carry only one set of chromosomes. A single gamete must combine with a gamete from a...

INTERNAL ANATOMY AND PHYSIOLOGY OF THE TESTES Tunica Vaginalis Outer serous membrane; has visceral and parietal layers with fluid in between. Tunica Albuginea Dense connective tissue; forms septa dividing the testis into lobules. Lobules Contain seminiferous tubules, where sperm production occurs. Seminiferous Tubules Site of spermatogenesis (sperm production). Straight Tubules Collect sperm from seminiferous tubules. Rete Testis Network of tubules; finalizes sperm maturation. E...

AMNIOTIC FLUID PHYSIOLOGY AND TESTING Amnion Provide a protective cushion for the fetus, allow fetal movement, stabilize the temperature, permit proper lung development. Volume of Amniotic Fluid Regulated by a balance between the production of fetal urine and lung fluid and the absorption from fetal swallowing and intramembranous flow; approximately 1L. Polyhydramnios Excess amniotic fluid from failure of fetus to swallow, associated with neural tube defects, fetal structural anomali...

PHYSIOLOGY TEST An increase in stored triglyceride molecules ________, and would be considered a/an ________ reaction. utilizes ATP; anabolic The final electron acceptor in aerobic cell respiration is ________. oxygen Glycolysis converts glucose into two ________ molecules. pyruvic acid Each pair of hydrogens generated in glycolysis are used to ________. reduce 2 molecules of NAD Anaerobic metabolism regenerates the ________ required for glycolysis. NAD Acetyl coenzyme A enables ...

ANATOMY & PHYSIOLOGY TEAS TEST Skeletal System functions Movement, protection and metabolism. Bone Types Long, short, flat and irregular. Long bones such as the humerus, ulna, radius, femur, tibia, and fibula, have hollow shaft containing marrow. Short bones such as the toe bones and collarbone, are wider than they are long. Irregular bones Such as the skull, knee, and elbow, are non symmetrical. Flat bones such as the scapula, ribs, and sternum, contain marrow but are not holl...

PHYSIOLOGICAL TESTS FOR BACTERIAL IDENTIFICATION Sugar Fermentation Tests an organism's ability to ferment glucose, commonly used to identify Gram - enteric bacteria. Mixed acid fermentation Also known as methyl red test; used to test fermentative organisms that convert sugars into various organic acids. Butanediol fermentation Also known as Vogues-Proskauer test; tests the ability of an organism to convert glucose to acetoin or butanediol. Nitrate Reduction Determines if an org...

MUSCLE PHYSIOLOGY TEST QUESTIONS actin The head of the myosin molecule binds to __ to form the crossbridge. tropomyosin What regulatory molecule on the thin filament covers the myosin head binding site on actin? troponin Which molecule on the thin filament has a binding site for calcium? ATP The binding of __ to the myosin head puts the crossbridge in its high energy conformation. ATP __ must bind to the crossbridge for it to disconnect from the actin molecule. ATP __ is responsibl...

ANATOMY AND PHYSIOLOGY PRACTICE TEST Which of the following terms describes the body's ability to maintain its normal state? (A) Anabolism (B) Catabolism (C) Tolerance (D) Homeostasis (E) Metabolism Homeostasis ) Each of the following is known to help prevent infection EXCEPT (A) hair in the nose (B) mucous membranes (C) osteoblasts (D) saliva (E) tears osteoblasts Each of the following mature cells has a nucleus EXCEPT (A) lymphocyte (B) monocyte (C) erythrocyte ...

PHYSIOLOGICAL TESTS Phenol Red Broth Medium for sugar fermentation testing with pH indicator. Sugar Fermentation Test Determines if bacteria can ferment specific sugars. Inverted Durham Tube Traps gas produced during sugar fermentation. Reversion Color change due to protein breakdown after sugar depletion. Decarboxylation Test Detects decarboxylase enzyme in Gram-negative bacteria. pH indicator used in decarboxylation tests Bromocresol Purple Phenylalanine Deamination Test Te...
