Upper Limb
The deltoid is innervated by this nerve
What is the axillary nerve?
The sciatic nerve branches into these two nerves that innervate muscles of the anterior and posterior leg
What are tibial and common fibular?
This biomarker of bone is generally higher in children
What is alkaline phosphatase?
This portion of the sarcomere only contains thin filaments
What is the I band?
This phenomenon occurs due to relative lack of ATP when muscles are in contractile state
What is rigor mortis?
This condition may result from damage of the upper trunk of C5-C6 nerves
What is Erb's palsy?
This muscle is generally weakened in a person who is positive for a Trendelenburg sign
Bonus: This nerve may be damaged in the above patient
What is the gluteus medius?
Bonus: What is the superior gluteal nerve?
Hyaline cartilage is primarily made up of this type of collagen
What is Type II collagen?
More of this ion exists inside of the cell (compared to outside the cell)
What is K+?
This helps to support the neck and serves as an attachment site for the trapezius and the rhomboid minor
What is the ligamentum nuchae?
These are the muscles that make up the rotator cuff
What are Supraspinatus, infraspinatus, teres minor, subscapularis?
The hamstrings originate from this bone
Bonus: These three muscles make up the hamstrings
What is the ischial tuberosity?
What are the biceps femoris, semimembranosus, semitendenosus
Most bones in the body are synthesized through this type of bone formation
What is endochondral?
Malignant hyperthermia may occur under anesthesia and is related to dysfunction of these sarcoplasmic channels
Bonus: This muscle relaxant is generally used as treatment
What are Ryanodine receptors?
Bonus: What is dantrolene?
A FOOSH is most likely to result in a fracture of this location
What is the distal radius?
Damage to the long thoracic nerve may result in this condition
What is winged scapula?
A valgus stress test will determine this type of knee injury
What is MCL?
Hyaline cartilage on articular surfaces lacks this
What is Perichondrium?
These are the four phases of an action potential
Bonus: This triggers an action potential
What are rising phase, overshoot, falling phase, undershoot?
What is Na+ influx
This will appear dull in T1 MRI imaging but will be bright in T2 MRI imaging
What is fluid?
A patient presenting with "Saturday night" palsy will have damage to this nerve, and will be unable to perform these actions
What is the radial nerve
What are elbow/wrist extension
This versatile foot joint is responsible for a variety of weight-bearing actions and is comprised of the TCN and calcaneocuboid joints
What is the transverse tarsal joint?
Acute osteoporosis increases production of these molecules (2), resulting in rapid resorption/bone loss
What are RANKL and M-CSF?
These two components of muscle spindles are sensitive to length change during contraction, which ensures that the muscle will respond appropriately to stretch
Alpha/gamma motoneurons
Neutral hand position (ideal functional position) involves wrist extension at this angle
What is 20 degrees?
