SHS 310 EXAM 1 QUESTIONS WITH CORRECT
ANSWERS 2026
1. Neurology-ANSWER- - Encode concept into verbal symbol (idea becomes a word)- Plan out
the sequencing of muscle contraction - Initiate movement
2. Respiration-ANSWER- Driving force (energy source)
3. Phonation-ANSWER- Sound generator
4. Articulation-ANSWER- Sound filter/shaper
5. Planes of Orientation-ANSWER- - Coronal-ANSWER- separates front from back- Sagittal-
ANSWER- separates left from right- Transverse-ANSWER- separates top from bottom
6. Directional Terms-ANSWER- - Superior/inferior- Proximal/distal- Lateral/medial
7. Animal Directional Terms-ANSWER- - Anterior/posterior- Ventral/dorsal- Rostral/caudal
8. Other Directional Terms-ANSWER- - Superficial/deep- Flexion/extension- Prone/supine
9. Afferent Nerve Fibers-ANSWER- Transmit sensory information from the body to the CNS (AKA
sensory fibers)
10. Efferent Nerve Fibers-ANSWER- Transmit motor impulses from the brain and spinal cord to
the periphery (AKA
motor fibers)
11. Decussation-ANSWER- Crossing of fibers at the midline
12. Check all statements that are true of "recoil"-ANSWER--ANSWER- 1. It is a passive force
exerted on the tissue.
2. Tissue is returning to its original rest position.
3. It occurs when muscles relax.
13. What role does Boyle's law play in respiration?-ANSWER- When we inhale, the pressure
within the
lungs decreases as the volume of air increases.
14. Describe how inspiration occurs.-ANSWER- When we inhale, we make the lungs larger which
will increase
, the volume. This decreases pressure in the lungs, and causes air flow inward from the
atmosphere.

15. Describe how expiration occurs.-ANSWER- When we exhale, it makes lungs smaller which
will decrease the
volume. This increases pressure in the lungs and causes air flow outward.
16. Intrapleural pressure-ANSWER- Pressure within the pleural cavity. Always negative,
increasing in negativity during
inspiration.
17. Negative alveolar pressure-ANSWER- During inspiration, expansion of the thorax decreases
the already nega
tive intrapleural pressure, and the increased lung volume results in a negative alveolar pressure.
18. Positive alveolar pressure-ANSWER- During expiration, this pressure differential is reversed,
with air escaping
the lungs to equalize the positive alveolar pressure with the relatively negative atmospheric
pressure.
19. Atmospheric pressure-ANSWER- Pressure of the atmosphere generated by its weight;
approximately 760 mm Hg.
20. Pelvic girdle-ANSWER-
21. Pectoral girdle-ANSWER-
22. Trachea-ANSWER- The trachea is a flexible tube composed of a series of 16 to 20 hyaline
cartilage rings. This tube runs
from the inferior border of the larynx for about 11 cm, where it divides to become the left and
right bronchial tubes.
23. Lungs-ANSWER- Two lobes within the chest wall where the exchange between CO2 and
oxygen happen.
24. Bronchioli-ANSWER- Smallest branches of the bronchi.
