Week 10 Neuro SCIs

grey matter = sensory and motor cell bodies, dendrtites, unmyelinated axons, interneurons, and synapses white matter = mainly myelinated axons dorsal root = all the sensory axons enter the spinal cord ventral root = all the motor axons exit the spinal cord

Myotome = refers to the muscles innervated by axons from a single spinal segment Dermatome = Refers to the area of skin innervated by axons from a single spinal segment Peripheral nerve field = Muscle or area of skin innervated by axon from an individual peripheral nerve Spinal nerve (PNS) = merger of dorsal and ventral roots

C6-C7 = wrist and elbow extensors C8-T1 = Long finger flexors and small hand muscles L3-L4 = knee extensors L4-L5 = knee flexion

<p>level or lesion, complete or incomplete lesion, tetraplegia or paraplegia</p> Signup and view all the answers

<p>Complete lesion = no sensory or motor function below the level of the leion Incomplete lesion = preservation of some sensory or motor function below the level of injury Tetraplegia = Involvement of all 4 extremities, trunk, and respiratory muscles Paraplegia = Involvement of all or part of trunk and both lower extremities</p> Signup and view all the answers

<p>C1-C3 = limitied head/neck movemet, require ventilator, total paralysis of trunk, UE and LE C4 = usually has head and neck control, may shrug shoulders C5-C6 = has movement in head, neck, shoulders, arms, and wrists. Can bend elbows and move wrists C7-T1 = Movement around elbows and fingers with limited hand function</p> Signup and view all the answers

<p>T2-T6 = Has normal motor function in head, neck, shoulders, arms, hands fingers. T7-T12 = Has abdominal control, able to perform unsupported seated activities, limited supported walking abilities L1-L5 = Walking can be viable function with help from braces S1-S5 = Various return of voluntary bladder and bowel functions</p> Signup and view all the answers

<p>Posterior Cord Syndrome = rare, usually occurs from tumor or infarction, motor control and crude, touch, pain, and temp are preserved. Touch and proprioception lost below lesion Central cord syndrome = Results from hyperextension and compressive injuries that cause cord swelling. Impairment function is UE&gt;LE. High % of patients will attain ambulatory function Brown-Sequard's syndrome/ Hemicord lesion = Can result from gun shot or stab wound. Ipsilateral paralysis and loss of fine touch and proprioception. Contralateral loss of crude touch, pain and temp sense Anterior cord syndrome = usually caused from cervical flexion. Complete motor function lost bilaterally. Complete loss of crude touch, pain, temp sensation bilaterally. Fine touch and. proprioception sensation are preserved</p> Signup and view all the answers
