|---|---|
| What is the difference between axial and appendicular muscles? | Axial muscles support and move the head, neck, and trunk; appendicular muscles move the limbs and stabilize the pectoral/pelvic girdles. |
| Name two major axial muscle groups. | Muscles of the head/neck (facial expression, mastication) and trunk (abdominal wall, erector spinae). |
| Give examples of appendicular muscles. | Deltoid, biceps brachii, quadriceps femoris, gluteus maximus. |
| What are the two main types of nervous system cells? | Neurons (signal transmission) and neuroglia (support, protection, nourishment). |
| What are the three functional types of neurons? | Sensory (afferent), motor (efferent), interneurons (integration). |
| Name one function of astrocytes. | Maintain blood-brain barrier and regulate nutrient exchange. |
| What structures make up the CNS? | Brain and spinal cord. |
| What structures make up the PNS? | Cranial nerves, spinal nerves, and ganglia |
| What are the divisions of the ANS? | Sympathetic (“fight or flight”) and parasympathetic (“rest and digest”). |
