Study Notes
Practice Test - Anatomy and Physiology
- Question 1: The sarcoplasmic reticulum stores calcium ions.
- Question 2: Overstretched myofibers prevent myosin heads from contacting actin, hindering contraction.
- Question 3: Calcium binds to troponin for skeletal muscle contraction.
- Question 4: T-tubules deliver action potentials for calcium release.
- Question 5: Acetylcholinesterase degradation is crucial for muscle contraction.
- Question 6: More sodium ions are outside the cell during resting membrane potential.
- Question 7: Fast saltatory conduction occurs along myelinated axons.
- Question 8: Myelinated neurons primarily exhibit saltatory conduction.
- Question 9: The frontal lobe is linked to decision-making.
- Question 10: Cerebral cortex folds are gyri; grooves are sulci.
- Question 11: Dura mater is the outermost brain protection layer.
- Question 12: Long-term potentiation alters neuron membrane potentials.
