Question

This assignment will give you practice drawing neuron pathways as they travel through the spinal cord.

Part 1 - Using the template attached, draw the 3 pathways/reflexes identified below. You may submit them as 3 separate drawings if you choose. When making your drawings, pay close attention to where you are placing your axons and your synapses (Hint: Remember the roles of white matter and gray matter as well as anterior, posterior, and lateral horns). Label your pathways 1-3.

1. An incoming sensory signal destined for the cerebral cortex of the brain

2. An outgoing motor command to the skeletal muscles of the lower limb

3. A polysynaptic, contralateral, spinal reflex arc

Explanation / Answer

The region of the brain that alerts the cerebral cortex to incoming sensory signals and is responsible for maintaining consciousness, awakening from sleep, works when you scratch palate, alertness.
