Clinically Relevant Anatomy of Spinal Nerves Flashcards
is loss of coordnation/balance/clumsiness a sensory or motor symptom
both
which spinal level has no significant cutaneous sensory axons
C1
which dermatome does the pubic symphysis correspond to
T12
where do the posterior rami suply
- synovial joints of vertebrae
- deep muscles of back
- strip of skin centrally down back and posterior neck
which nerve roots are the iliohypogastric and ilioinguinal nerves made up of
half of L1 each
which nerve root is the subcostal nerve made up of
T12 anterior ramus
named nerve cutaneous innervation of the head and neck
little goats tread softly
where is the nerve point of the neck found
midpoint of posterior border of SCM
named nerve cutaenous innervation
referred pain from diaphgram
- C345
- supraclavicular nerves C3+4 supply cuaneous innveration to shoulder
- –> referred pain from diaphgram/liver pathology
through which spinal nerves is pain from myocardium, eg heart attack, referred
T1+2 anterior rami
named nerve cutaenous innervation
clinical testing of myotomes C5-T1
clinical testing of myotomes L3-S2
outline the steps in a tendon reflex
- eg patellar tendon
- tap tendon
- stretch muscle fibres
- initiate AP in anterior rami axons in femoral nerve
- sensory APs conducted to dorsal horn of L3
- axons pass into anterior horn and synapse on LMNs that supply quadriceps
- APs conducted via LMN axons in femoral nerve to reach quadriceps NMJ
- muscle contracts to extend knee joint
C2 dermatome
back of scalp and adam’s apple
C3 dermatome
back of neck and jugular notch
C4 dermatome
clavicle and shoulder tip
middle finger dermatome
C7
badge patch dermatome
C5
anterior leg dermatome
posterior leg dermatomes
cervical plexus
