Flashcards in Chamberlain Review Deck (53)
At which spinal level does the spinal cord end? The dural sac?
What happens to the notochord in the adult? What happens to the neural tube?
Nucleus pulposus of disc
Becomes the ventricles and central canal of spinal cord.
The neural crest cells go on to form what?
The peripheral nervous system
What are the muscles supplied by the radial nerve? (BEST)
Brachioradialis (perfect for holding beer), extensors, supinators, triceps
The radius articulates with which carpal bones?
Scaphoid, lunate, and triquetrum
What are the landmarks of the anatomical snuffbox?
Extensor pollicis longus and brevis
What are the muscles supplied by median nerve? (L(L)OAF)
Lumbricals 1 & 2 (LL)
Abductor pollicis brevis
Flexor pollicis brevis
Intrinsic muscles of the hand: All for one and one for all.
Thenar: Abductor pollicis longus, Flexor pollicis brevis, Opponens pollicis, Adductor pollicis brevis
Hypothenar: Opponens digit minimi, flexor digiti minimi, abductor digiti minimi
Where does flexor digitorum superficialis (middle layer) and flexor digitorum profundus (deep layer) insert?
Superficialis, splits and inserts on middle phalanges
Profundus, inserts in distal phalanges (deep layer)
Insertions on the extensor side of the hand begin where?
At the MCP, the extensor expansion
Name the condition: Chronic irritation causes a nodule to form along the flexor tendons preventing smooth action of the tendon and may lock finger in flexed position.
Name the condition: lost extensor connection to distal phalanx, can't extend distal phalanx
What do the the palmar and dorsal interossei do?
Name the hand deformity for the lesion:
Ape hand/Apostol - loss of flexion of metacarpal 1,2,3, weak flexion of 4, 5, can't bring thumb and pinky to touch.
Name the hand fracture:
FOOSH on extended hand
FOOSH on flexed hand
Colle's - dinner fork deformity
The neural crest cells go on to form what structures?
CAlifornia MOTEL PASS:
Enterochromaffin cells - Adrenal medulla
Parafollicular C cells/Pseudounipolar cells
Spiral septum -Aorticopulmonary septum
Describe the SSX of neurofibromatosis type 1.
Cafe au lait, iris pigmentation (lisch nodules), neurofibromas
The alar (sensory) plate becomes the _____ horn. The basal (motor) plate becomes the ____ horn.
Remnants of Rathke's pouch may give rise to what condition?
What are the functions of the following areas of the nucleus:
Hunger (gas cap)
Satiety (gas tank)
MC form of spina bifida.
Occulta - hair
Spinous process terminates at a higher level.
What maternal serum level is elevated with neural tube defects?
Know the ossification ages: (Every potential anatomist should know when)
Branchial plexus runs from what vertebral levels?
What n. innervates supra and infra spinatus?
What is the first branch off of the aorta?
Which side is the brachiocelphalic?
ABCS - Aortic arch gives Brachiocephalic trunk, Common Carotid, Subclavian
