VESSEL ACTIVITIES (for brain) 1. Which arteries on your list are the last to supply blood to the brain? Write all answers 2. Which vessel on your list would be the vessel to collect blood from the Superior Sagittal Sinus? Skip #3-6 for now 3. Where-could-you-apply pressure to stop hemorrhaging anywhere in the Leg-bom-a big gash-somewhere along the LE? 4. Take-off your shoe-Find-the-pulse (artory-from-your-list-see notes closest to your Big-Toe 5.On-your-partner-by-to-find-2-other puisee-Write-which-2-you-can hopefully ind 6. A blood clot (wombus) in the Great Saphenous Vain that breaks-loose (embolus) would occlude arterioles-in-which-organ? Would-an-embolus from the atrium-occlude-artorioles in the heart-orbran PERIPHERAL NERVE ACTIVITIES Write all answers 1. Below which vertebral level would it be safe to give a spinal canal injection (e.g. epidural or spinal tap) without risk of poking the Conus Medullaris? Why is L5 spinal nerve considered part of the Cauda Equina, but not C5 nor T5 spinal nerves? 2. List the plexus that innervates the UE AND which ventral rami (spinal nerve levels) are at the beginning of that plexus. List the combined plexus that innervates the LE AND which ventral rami are at the beginning of that plexus. 3. Which peripheral nerve innervates the UE extensors? Which peripheral nerve would most likely require surgery in its tunnel due to thenar (anterior thumb muscles) weakness? Which nerve innervates most of the intrinsic muscles of the palm & hypothenar (anterior ulnar hand muscles) regions? (Read! Do NOT just go by the pictures) 4. Imagine the buttock divided into 4 quadrants. Which is the safest quadrant to give an injection without injuring the Sciatic Nerve? 5. One of your patient's eyes barely moves around and the pupil is 'fixed & dilated' (as opposed to PERLA- Pupils: Round, Reactive to Light & Accommodation). Which peripheral nerve is most likely compressed? 6. A growing tumor compressing the contents of the Internal Auditory Canal would most likely create which kind of symptoms (search for which nerveg would be compressed and thus which functions the nerves could not perform well)?

Down 8 & 10 (not shown in image): 8. This type of tract carries efferent information from the brain, down the cord, to terminate on a lower motor neuron. 10. Three columns of white matter run up and down the spinal cord. Each column is called a

Head trauma often leads to greatly increased pressure inside the skull, so doctors must drill into the skull and drain off some CSF to reduce the pressure. Where do they need to drill in order to do this? During brain surgery to resect (remove) a tumor, surgeons "map" the brain by stimulating different regions of the cerebral cortex while the patient is awake and observing how the patient responds. If the surgeon stimulates the brain and the patient moves his left arm, where in the brain must the doctor be stimulating? In an adult human, what would you find if you drilled into the L4 level of the vertebral column? Where would you find the cell bodies of the cells responsible for motor function in the brain (aka. the upper motor neurons)? In all the afferent sensory pathways below the neck, where is the cell body of the first-order neuron found? The regions of skin that are monitored for sensation by a pair of spinal nerves at a specific level in the spinal cord (e.g. T7) are called what? Why don't you feel the shirt you are wearing unless you focus your attention on it? There are two possible reasons.
16. A Josh who ran in the New York City marathon noticed that while his legs were moving in a normal automatic rhythm, he was still able to relax and think about other matters. What part of the brain is most likely in charge of the movement of his legs as he let his mind wander? Medulla Superior colliculi Red Nuclei Pons Substantia Nigra 19. Saltatory conduction is seen in _______ axons and is caused by action potentials occurring in the _________. Myelinated; nodes of Ranvier Myelinated; axon hillock Unmyelinated; nodes of Ranvier Myelinated; myelinated regions of the axon None of the above 22. The release of an activating neurotransmitter from one presynaptic neuron is most likely to cause which of the below results? An IPSP Neural summation An EPSP Always causes an action potential Neural facilitation 28. Which of the below statements is FALSE regarding a local (or graded) potential? It can lead to depolarization of the plasma membrane. It can lead to hyperpolarization of the plasma membrane. Can fizzle out if threshold is not reached. It can be activated by the release of ligands, stretch of receptors, or spontaneously. It always leads to depolarization and an action potential. 34. A network of capillaries in the brain that produces cerebrospinal fluid is called the ____. Dural sinus; ependymal cells Choroid plexus; microglia Spinal canal; astrocytes Choroid plexus; ependymal cells Arachnoid villus; astrocytes 36. Which area of the neuron is the site of action potential transmission in the axon? Body Dendrites The axon hillock The synaptic knobs Dendritic spines The neurons that cause the heart rate to increase most likely have cell bodies found in this area? Dorsal horn Dorsal root ganglion Ventral horn Lateral horn Medial horn
