Anatomy
These muscles are innervated by the superior gluteal nerve.
Gluteus medius, minimus, and tensor fascia latae.
What can cause ipsilateral loss of discriminative touch & proprioception combined with contralateral analgesia
Spinal cord hemisection (Brown-Sequard Syndrome)
These cells give rise to cells that form most of the peripheral nervous system and autonomic nervous system.
Neural crest cells
Injury to this nerve results in weakness in dorsiflexion that causes foot drop and prompts steppage gait.
common fibular (peroneal) n.
This nerve is often damaged with a fibular neck fracture.
Common Peroneal (Fibular) Nerve
These muscles form a conjoint tendon called the pes anserinus.
Sartorius m. (Ant.)
Gracilis m. (Med.)
Semitendinosus m. (Post.)
Non conscious proprioception from the lower body and trunk are carried by this tract
dorsal spinocerebellar tract
This adult structure arises from the rhombic lips
Cerebellum
A biker has lost sensation of the skin of his big toe over the plantar side. Which nerve is likely damaged?
Medial plantar n.
A patient with a deep knife wound in the
buttock walks with a waddling gait that is
characterized by the pelvis falling toward
one side at each step. Which nerve is damaged?
The superior gluteal nerve
This muscle corrects medial deviation of flexor digitorum longus tendon.
Quadratus plantae m.
If this structure were damaged, a patient would present with bilateral pain and temperature sensation loss below the level of the damage
Anterior White Commisure? (Spinothalamic decussation in spinal cord)
This layer of the neural tube will eventually form the cells that line the central canal of the spinal cord.
Ventricular zone (neuroepithelial layer)
These are the contents of the popliteal fossa (Bonus: in order from superficial to deep)
A patient presents with sensory loss on
adjacent sides of the great and second toes
and impaired dorsi flexion of the foot. These
signs probably indicate damage to which nerve?
Deep fibular (peroneal) n.
The sciatic nerve enters the gluteal region between these two muscles.
Piriformis m. and superior Gemmellus m.
The somatotopy of the internal capsule from lateral to medial is
Foot, Leg, trunk, Hands/Arm, Neck
The cells contained in this plate give rise to sensory neuroblasts
Alar (sensory, dorsal) plate
The dorsalis pedis artery arises from this artery.
anterior tibial artery
A construction worker falls feet fi rst
from a roof. He sustains a fracture of the
groove on the undersurface of the susten-
taculum tali of the calcaneus bone. Which muscle tendon is most likely
torn?
Flexor hallucis longus
A chef drops a knife that then penetrates his right foot. He has trouble moving his 4th toe toward his pinky toe. What muscle did he likely damage?
Dorsal interosseous m.
What artery supplies the spinalthalamic and medial lemniscus tracts in the midbrain?
Proximal PCA
A tumor that causes unexplained hypertension and releases too much epinephrine and norepinephrine arises from these type of nerve cells.
Trunk nueral crest cells
These structures (from anterior to posterior) pass deep to the flexor retinaculum in the tarsal tunnel.
Tibialis posterior, flexor digitorum longus, posterior tibial vein/artery, tibial nerve, and flexor hallucis longus
A patient with hereditary blood clotting
problems presents with pain in the back of
her knee. An arteriogram reveals a blood clot
in the popliteal artery at its proximal end.
Which artery will still allow
blood to reach the foot?
Lateral circumflex femoral
