I Promise You'll Be Spine...al Cord :)
This structure is an extension of pia mater that anchors the spinal cord to the coccyx
This muscle's action is to elevate the scapula and inferiorly rotate the glenoid cavity
What is Levator Scapulae?
The ACL functions to prevent this from occurring
What is prevention 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
What is the Somatic Sensory division?
There are typically 206 bones in the human body, so we categorize them into two components. This component consists of the cranium, thoracic cage, and the vertebral column
What is the Axial Skeleton?
This type of anesthesia is injected into the epidural space, and gives slower longer lasting effects
What is Epidural anesthesia?
If there is weakness or thinning in this spinal ligament, there is a higher chance of herniating an IV disc
What is the Posterior longitudinal ligament?
The fist split of the Sciatic nerve branches into these two nerves
What are the Tibial n. and Common Fibular n.?
The Somatic motor division provides innervation to skeletal muscle for movement. The cell bodies originate in the ventral hord of the spinal cord and the axons then leave through these structures before becoming the spinal nerve.
What are ventral rootlets and roots?
There are 5 different types of bone shapes; this type develops within tendons due to excessive wear and changes of angle
Bonus: 100 extra points if you can give an example of this type of bone
Sesamoid bone
Bonus: Patella or Pisiform
This spinal nerve carries no sensory neurons, and only contributes motor innervation to skeletal muscle
What is spinal nerve C1?
Latissimus dorsi has it's lateral attatchment at this location
The typical angle of inclination in a young adult is 120 degrees. This is the term for an angle of inclination greater than 140 degrees
What is Coxa valga?
Plexuses are bundles of axons from multiple different spinal nerves, and all plexuses arise from these structures
What are 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?
What is Plantarflexion?
Sympathetic motor neurons all originate at these spinal cord levels
What are T1-L2?
These muscles are members of the Erector spinae group:
The tendons of these three muscles comprise what is known as the Pes Anserinus?
There are many different pathways of sympathetic innervation. These nerves function to cause bronchodilation
What are the Inferior Splanchnic nerves?
This virus lies dormant in the dorsal root ganglia and spread to the spinal cord, and eventually to the dermatome causing a painful rash
What is the Shingles Virus?
A patient was in a severe car accident, and is is no longer able to inspire on their own. This is due to an injury at these spinal cord levels
What is C3, 4, 5?
Demifacets are small attachment points on the vertebral body for rib articulation, these vertebrae are the ones that contain demifacets
What are T1, T2-T9, T10?
The Dorsal and Plantar venous arches can drain into any of these three veins

Bones grow in length due to this type of process of ossification
