|---|---|---|---|---|---|
| Describe how the nervous system is functionally divided into the Somatic and the Autonomic nervous systems. What is the function of each functional nervous system? | show 🗑
|
||||
| Which senses are part of the somatic nervous system? | show 🗑
|
||||
| Where are the control centers for each of the 5 somatic sensations? | show 🗑
|
||||
| General route a somatosensory sensory pathway takes through the nervous system to relay information from a facial sensor to the cerebral cortex. | show 🗑
|
||||
| show | CNS by cranial nerves: olfaction, vision, audition & equilibrium, somatosensation, gustation
CNS by spinal nerves: somatosensation
🗑
|
||||
| Describe how spinal nerves, plexuses, and peripheral nerves are connected. | show 🗑
|
||||
| show | cervical plexus C1 to C5: throat/neck muscles & sensors
brachial plexus C5 to T1: upper limb muscles & sensors
lumbar plexus L1 to L4: lower abdomen/parts of thigh muscles & sensors
sacral plexus L4 to S4: buttocks/lower limb muscles & sensors
🗑

||||
| General route a somatosensory sensory pathway takes through the nervous system to relay information from a sensor to the cerebral cortex | show 🗑
|
||||
| show | Ascending pathway
🗑
|
||||
| What does it mean for a pathway to be ipsilateral or contralateral? Which sensory pathways tend to be ipsilateral or contralateral? | show 🗑
|
||||
| What does it mean for a neuron to decussate? | show 🗑
|
||||
| What does it mean for pathways to be “topographically” arranged in the cerebral cortex? | show 🗑
|
||||
| What does it mean to have uneven matching in the topographical arrangement between the sensors and cortex? | show 🗑
|
||||
| What are association and multimodal areas, and what do they do? | show 🗑
|
||||
| Motor pathway's general route through the nervous system to relay information from the motor cortices to skeletal muscles | show 🗑
|
||||
| show | Skeletal Muscle
🗑
|
||||
| Is a spinal motor pathway considered an ascending or descending pathway? | show 🗑
|
||||
| Which motor pathways tend to be ipsilateral or contralateral? | show 🗑
|
||||
| show | Sensory information "flows" from the primary cortex to association cortices to multimodal association cortices
🗑
|
||||
| show | Simple pathways that do not include a cerebral cortex (not a cortical pathway). Reflexes can use spinal or cranial nerves.
🗑
|
||||
| Describe the difference between a cortical pathway and a reflex. What are the advantages and disadvantages of a cortical pathway vs. a reflex? | show 🗑
|
||||
| Pathway of a withdrawal reflex | show 🗑
