Anatomy and Physiology I
Multiple Choice Questions, Answers & Explanations
1. Which type of cartilage is usually associated with compact bone function and development?
A. Elastic cartilage
B. Calcified cartilage
C. Hyaline cartilage ✓
D. Fibrous cartilage
Explanation: Hyaline cartilage forms the cartilage model used during endochondral bone formation and is important
in skeletal development.
2. Which of the following is the latissimus dorsi?
A. Triceps brachii
B. Articular cartilage
C. Latissimus dorsi
D. Other choices depend on the missing image.
Explanation: The question depends on an image with arrows identifying anatomical structures. The image is not
available in the extracted text, so the exact option cannot be confirmed.
3. Where is the cerebrospinal fluid (CSF) formed?
A. Veins
B. Capillaries
C. Aorta
D. Ventricles ✓
Explanation: CSF is produced mainly by the choroid plexuses within the ventricles of the brain.
4. Which term describes the mechanism by which an impulse in a presynaptic neuron signals
the postsynaptic neuron?
A. Saltatory conduction
B. Synaptic transmission ✓
C. Electrical conduction
D. Neurotransmission
Explanation: Synaptic transmission is the process by which a signal passes from a presynaptic neuron across a
synapse to a postsynaptic cell.
5. What provides the primary protection for the inner living skin from the damaging effects of
ultraviolet rays?
A. The secretion of sebum by the sebaceous glands
B. Granules containing eumelanin and pheomelanin ✓
C. The presence of keratinized dead cells in the stratum corneum
D. The absorption of vitamin D by the epidermis
Explanation: Melanin pigments absorb ultraviolet radiation and help protect the DNA of living epidermal cells.
