Review Questions Flashcards
Sensory loss to the 4th and 5th finger would cause concern for which structure?
Would you expect the damage to be before the plexus? At the elbow? Or in the hand?
And why?
Ulnar Nerve
In the Hand
Damage in any of the other places would present with sensory loss elsewhere, not just the 4th and 5th fingers.
What is found in the dorsal root ganglion?
Sensory neuron cell bodies

First rib, teres major
What makes up the walls of the axilla?
Serratus medially, pec major and minor and subclavian m. Anteriorly, Lats teres major and subscap posteriorly

Ant and post circumflex artery
Ratio of GH to scapular movement?
2:1

Contents?
Long head of triceps, teres minor, teres major, surgical neck of humerus.
Post. Humeral circumflex aa. & axillary nn.
Borders of triangular space?
Long head of triceps, teres minor, teres major. Contents? Scapular circumflex aa.
Triangular interval?
Long head of triceps, lat head of triceps, teres major. Contents? Profounda brachii aa. & radial nn.
Sagittal plane occurs in which direction, around which axis?
Ant-Post, Med-Lat axis
Frontal plane
Left to right direction around ant-post axis
Horizontal plane? Horizontally

What are 2 ways to classify joints?
Structure and function
What are the three types of movement classification?
How much movement is allowed by each?
Diarthrosis, amphiarthrosis, synarthrosis
Full, some, none (respectively)
Name the different types of fibrous joints and give an example of each
gomphosis: teeth
syndesmosis: tib-fib, interosseous membrane
suture: skull sutures
Cartilaginous joints:
symphysis: pubic symphysis, IV discs
synchondrosis: epiphyseal plates, costochondral
7 distinguishing characteristics of synovial joint:
synovial membrane, bursa, ligaments, nerve supply, blood supply, joint capsule, articulate cartilage
Name each type of synovial joint, how much movement is allowed, give an example.
hinge: 1* of freedom; elbow
- pivot: 1; atlanto-axial
- saddle: 3; thumb (metacarpal-carpal joint) be prepared for questions on why it’s 3, kids never get it at first.
- ball n socket: 3; hip, shoulder
- plane: 3* (same here, be prepared); vertebral facets, carpals on carpals, tarsal-tarsal
- condyloid: 2*; MCP, knee
What is more medial, basilic or cephalon vein?
What structure connects these?
Basillic vein
Median cubital vein
Does the brachial aa run in the ant or post compartment of the arm
Anterior
What is the contents of the spiral groove?
Why is this a concern?
Profounda brachii aa. and radial nn.
Area susceptible to damage with a fx
Where is the next anatomical landmark that is used to find the radial nn. after the spiral groove?
Lateral forearm, between brachioradialis and brachialis
What muscle does the musculocutaneous nn. pierce in the arm
