The anatomical divisions of the nervous system
What are the the central, peripheral, and enteric nervous system
Regions of spinal cord
What is cervical, thoracic, lumbar, and sacral
Main regions of the brain
What are the cerebrum, cerebellum, diencephalon, and brainstem
Where optic nerves converge
What is the optic chiasm
The three levels of neurons in sensory pathways
What are first order neurons, second order neurons, and third order neurons
The structural classifications of neurons
What are the anaxonic neurons, bipolar neurons, unipolar neurons, and multipolar neurons
What are the dura mater, arachnoid mater, and pia mater
Rounded elevations vs. shallow depression vs. deep grooves
What are gyri vs. sulci vs. fissures
Motor (eye movements)
*3 answers
What is the oculomotor nerve, trochlear nerve, and abducens nerve
Sensory homunculus
What is a functional map of primary somatosensory cortex. The area devoted to a particular region is proportional to the density of sensory neurons.
Functions of the autonomic nervous system
What is subconscious actions, contractions of smooth and cardiac muscle, and glandular secretions
Connective tissue layers around spinal nerves
What are the epineurium, perineurium, and endoneurium
Three largest dural folds
What are the falx cerebri, tentorium cerebelli, and falx cerebelli
Origin of trochlear nerve
What is the midbrain
Referred pain
What is a feeling of pain in an uninjured part of body when pain originates at another location
The types of neuroglia in the CNS and PNS
What are astrocytes, ependymal cells, oligodendrocytes, microglia, satellite cells, and schwann cells
Shingles
What is a rash formed by the reactivation of chicken pox virus on the dermatome associated with the spinal nerves affected by the disease.
Chronic traumatic encephalopathy (CTE)
What is a neurodegenerative disorder from repeated blows to the head. Often seen in athletes that have played ice hockey, American football, soccer, rugby, etc. Symptoms include behavior problems, mood problems, problems with thinking, and dementia.
Bell's Palsy symptoms
What is the paralysis of facial muscles on affected side and loss of taste sensations from anterior two thirds of tongue
Explanation of the spinothalamic pathway
What is first order neurons entering spinal cord and synapsing within posterior horns, second order neurons crossing to opposite side of spinal cord before ascending, third order neurons in ventral nuclei of thalamus, and lastly, the primary somatosensory cortex.
Steps of nerve regeneration
What is:
1. Fragmentation of axon and myelin occurs in distal stump
2. Schwann cells form cord, grow into cut, and unite stumps. Macrophages engulf degenerating axon and myelin.
3. Axon sends buds into network of Schwann cells and then starts growing along cord of Schwann cells.
4. Axon continues to grow into distal stump and is enclosed by Schwann cells.
The major brachial plexus nerves
What are the musculocutaneous nerve, median nerve, ulnar nerve, axillary nerve, and radial nerve
Types of ischemic and hemorrhagic strokes
Whatare thrombotic ischemic, embolic ischemic, lucanar ischemic, intracerebral hemorrhage, and subarachnoid hemorrhage.
All the cranial nerves
What is olfactory, otpic, oculomoter, trigeminal, trochlear, abducens, facial, vestribulocochlear, glossopharyngeal, vagus, accessory, hypoglossal.
List of the differnet sensory/motor pathways
What are the Somatic sensory pathways: spinothalamic, posterior column, and spinocerebellar pathway; and the somatic motor pathways: corticospinal, medial, and lateral pathways
