This structure is an extension of pia mater that anchors the spinal cord to the coccyx
Filum terminale
This muscle's action is to elevate the scapula and inferiorly rotate the glenoid cavity
Levator Scapulae
The ACL functions to prevent this from occurring
prevent of posterior displacement of the femur
The peripheral nervous system is split up into different sections depending on their function. This section of the nervous system is responsible for receiving external stimuli such as temperature, touch, pain, and the special senses
Somatic Sensory division
Tom Dick and A Very Nervous Harry is a common neumonic to remember what structures of the leg?
Tibialis Posterior
Flexor Digitorum Longus
Posterior Tibial Artery & Vein
Tibial Nerve
Flexor Hallucis Longus
Anesthesia can be injected into the epidural space, and affects these spinal cord structures
Spinal nerve roots of Cauda equina
If there is weakness or thinning in this spinal ligament, there is a higher chance of herniating an IV disc
Posterior longitudinal ligament
The fist split of the Sciatic nerve branches into these two nerves
Tibial n. and Common Fibular n.
The Somatic motor division provides innervation to skeletal muscle for movement. The cell bodies originate in the ventral horn of the spinal cord and the axons then leave through these structures before becoming the spinal nerve.
ventral rootlets and roots
Carmella goes skiing 5 times a year, and recently has been having severe pain in the top of her foot and the space in between her first two toes. This could be due to injury to what nerve?
BONUS 100 Points: explain to me what structure is compressing the nerve here to cause injury
Deep Fibular nerve
BONUS: extensor retinaculum
This spinal nerve carries no sensory neurons, and only contributes motor innervation to skeletal muscle
spinal nerve C1
Latissimus dorsi has it's lateral attatchment at this location
Superior humerus
Braxton was severely sideswiped during his football game. His doctors told him that he has whats known as the terrible triad injury. What structures are injured?
ACL, MCL, and medial meniscus
Plexuses are bundles of axons from multiple different spinal nerves, and all plexuses arise from these structures
ventral rami
OH NO! I'm driving down a dark road and I'm about to hit an opossum, so I slam my foot down on the brake! This is an example of what kind of movement?
Plantarflexion
Sympathetic motor neurons all originate at these spinal cord levels
T1-L2
These muscles are members of the Erector spinae group:
Iliocostalis, Longissimus, Spinalis
The tendons of these three muscles comprise what is known as the Pes Anserinus?
Sartorius, Gracilis, and, Semitendinosus
There are many different pathways of sympathetic innervation. Some nerves descend the sympathetic chain and innervate what structures
Lower trunk, and Lower limb
Dragon had a wild weekend in Vegas, and recently just tested positive for gonnorhea. His school nurse told him he has to get a shot in the superolateral quadrant of the gluteus to cure it. It must be done in this specific location to avoid injury to what nerve?
Sciatic Nerve
MacKenseaighe was in a skiing accident and broke her fibula. She now cannot dorsiflex, or evert her foot causing it to "drop" when she walks. This is caused by an injury to this nerve
Common Fibular Nerve
Demifacets are small attachment points on the vertebral body for rib articulation, these vertebrae are the ones that contain demifacets
T1-T10
The Dorsal and Plantar venous arches can drain into any of these three veins
Anterior tibial, Posterior tibial, and Fibular v.

The patellar reflex is done is almost every physical exam to test what nerve and what spinal levels?
Femoral n. and L2-L4 spinal levels
