Published	08/12/2024	{{c1::Axons}} can deliver signals to/from brain/spinal cord to/from target - motor (brain to target) vs. sensory (target to brain)
Published	08/12/2024	Explain the clinical relevance of spinal cord segments, dermatome, myotome, peripheral nerve territories, and referred pain.
Published	08/12/2024	{{c1::Cranial nerves (12 pairs)}} have specific functions - motor, sensory, or both
Published	08/12/2024	{{c1::Spinal nerves (31 pairs)}} are always both motor and sensory
Published	08/12/2024	Cervical ({{c1::8}}), thoracic ({{c1::12}}), lumbar ({{c1::5}}), sacral/coccygeal ({{c1::6}}) → cervical plexus, brachial plexus, intercostal nerv…
Published	08/12/2024	{{c1::Dermatome}}: all skin innervated by that spinal nerve on that side
Published	08/12/2024	{{c1::Myotome}}: all muscles innervated by that spinal nerve on that side
Published	08/12/2024	{{c1::Peripheral}} nerve territories: do not directly match dermatomes/myotomes
Published	08/12/2024	4 regions where anterior rami (spinal nerve branches) recombine called plexus of nerves: {{c1::cervical, brachial, lumbar, sacral }}

Published	08/12/2024	Peripheral nervous system
Published	08/12/2024	{{c1::Arteries}}: away from heart, thick smooth muscle and elastic fibers for high pressure
Published	08/12/2024	{{c1::Veins}}: towards heart, valves to prevent backflow, thinner smooth muscle for lowerpressures
Published	08/12/2024	{{c1::Neurovascular bundles:}} arteries, veins, and nerves run in parallel enclosed by a fascial/vascular sheath

Published	08/12/2024	Fascia:
Published	08/12/2024	{{c1::Deep}} fascia is tough, mostly tendinous dense regular connective tissue, no fat - Overlies muscles and varies in thickness
