how are the cranial nerve components split up? |
3 motor 3 sensory |
|
|
what are the components of the motor part? |
1) somatic motor - GSE 2) visceral motor (parasymp) GVE 3) brachiomotor - SVE |
|
|
somatic motor: - structures/function? -blobs of grey? |
1) skeletal muscle somites (eye, tongue) 2) CN 3, 4, 6, 12 - these nerves happen to be near the midline |
|
|
left side hypoglossal nerve palsy problem with which side of nerve? |
left |
|
|
visceral motor: -structures/function? -blobs of grey? |
1) glands/smooth muscle (head/thorax) 2) CN 3(pupillary sphincter/cilliary muscle) 7 (submandibular, lingual) 9 (parotid gland) 10 (glands/smooth muscle of viscera) heart, airways, lungs |
|
|
brachiomotor: -structures/function? - blobs of grey? |
1) jaw, face, pharynx, larynx, head/shoulders branchial arch musculature 2) CN 5, 7, 9, 10, 11 |
|
|
branchiomotor: CN 5, 7, 9, 10, 11 functions? nucleus collectively called (CN 9,10,11)? |
CNV: mylohyoid, t. tympani, t. palatini, ant. digastric CNVII: stapedius, facial muscles CNIX: swallowing CNX: swallowing, speech, palate elevation CNXI: speech, palate elevation 2) nucleus ambiguus |
|
|
what are the 3 sensory components? |
1) general sensation - CN V nuclei 2) special and general visceral sensation: taste and input from organs 3) special "head" sensations: smell, vision, hearing (another lecture) |
|
|
general sensation: mesencephalic nucleus - what sensations? principal nucleus - what sensations? spinal nucleus - what sensations? |
1) propioception - jaw jerk 2) discriminative touch, vibration 3) pain, temp |
|
|
special and general visceral sensations: nucleus of tractus solitarius - what sensation? - which CNs involved? |
1) taste - from CN 7 and CN 9 2) CN 7, 9, 10 |
|
|
CN IX & CN X - commissural nucleus involved in? |
IX - carotid sinus/body X - aortic arch, pulmonary stretch receptors |
|
|
lower motor neuron lesion of CN 7 - weakness where? |
lower + upper face weakness same side |
|
|
upper motor neuron lesion CN 7? |
lower face weakness opposite side |
