BIOMEDICAL SCIENCE 100 LAB: ORGAN SYSTEMS

1. System = _________________________________________
   
   • on models, etc., identify: brain (including cerebrum & brainstem), spinal cord, spinal nerves
   • in microscope, identify: neurons, neuroglia (“glial cells”)
   • Question: Which are more numerous, neurons or neuroglia? Which are specialized for generating and transmitting electrical signals?





2. System = _________________________________________
   
   • on models, etc., identify: heart, aorta, inferior vena cava
   • in microscope, identify: cardiac muscle fibers
   • Question: True or false? In cardiac muscle tissue, the muscle fibers are organized into a network.





3. System = _________________________________________
   
   • on models, etc., identify: larynx, trachea, primary bronchi, lungs
   • in microscope, (view trachea, not esophagus), identify: mucosa, cartilage
   • Question: What is a "mucosa?"





4. System = _________________________________________
   
   • on models, etc., identify: deltoid, gluteus maximus
   • in microscope, identify: skeletal muscle fibers
   • Question: Why are the cells in muscle tissue often called "fibers?"





5. System = _________________________________________
   
   • on models, etc., identify: kidneys, ureters, urinary bladder, urethra (see on both male and female at Station 9)
   • in microscope, identify: renal tubules
   • Question: What is a "tubule?"





6. System = _________________________________________
   
   • on models, etc., identify: occipital bone, vertebra, humerus, femur
   • in microscope, identify: osteocytes
   • Question: What is the English translation of "osteocytes?"





7. System = _________________________________________
   
   • on models, etc., identify: stomach, liver, gall bladder, pancreas, small intestine, large intestine
   • in microscope, identify: liver lobules
   • Question: What fluid passes through the liver lobules?





8. System = _________________________________________
   
   • on models, etc., identify: pituitary gland, thyroid gland, pancreas, adrenal gland, ovaries, testes
   • in microscope, identify: pancreatic acini, pancreatic islets
   • Question: Which component of the pancreas - the acini or the islets - secretes hormones? Which component secretes digestive fluids?





9. System = _________________________________________
   
   • on models, etc., identify: on models, etc., identify: (male) testes, ductus (vas) deferens, penis, urethra; (female) ovary, uterine tube, uterus, vagina
   • in microscope, identify: ovarian follicle, secondary oocyte
   • Question: What is the common term for an "oocyte?"





10. System = _________________________________________
    
    • on models, etc., identify: tonsils, spleen, lymph nodes
    • in microscope, identify: lymphocytes
    • Question: What is the function of lymphocytes?





11. System = _________________________________________
    
    • on models, etc., identify: skin (including dermis and epidermis)
    • in microscope, identify: dermis, epidermis
    • Question: When viewing a micrograph of skin, how can you easily find the boundary line between the dermis and the epidermis?
