|
|
Term

|
Term
What are the Scapular borders?
-What do the terms mean? |
|
Definition
-Medial (vertebral) [closest to vertebral column]
-Lateral (axillary) [armpit]
-Superior -- intersects laterally with the coracoid process |
|
|
Term

-What do the terms mean? |
|
Definition
Inferior -- level of T7
Superior -- region fo the levator scapulae
Lateral -- expands to become the glenoid fossa and articulates with the humeral head |
|
|
Term

-Attachment? |
|
Definition
upper border of glenoid and base of coracoids
-Attachment for long head of biceps |
|
|
Term

Attachment? |
|
Definition
upper end of lateral border of scapula below glenoid fossa
-attachment for long head of triceps |
|
|
Term
|
Definition
| long bond of the upper arm--also known as the brachium |
|
|
Term
| What are the tubricles of the humerus? |
|
Definition
-greater tuberosity -extends beyond the lateral border of the acromion
-lesser tuberosity -- insertion for the subscapularis muscle
(seperated by the intertubercle or bicipital groove) |
|
|
Term
What are the greater tuberosity and the lesser tuberosity of the humerous separated by?
-What does this structure allow? |
|
Definition
Tubercles are seperated by the intertubercle or bicipital groove.
-allows for long head of biceps brachii tendon to pass through |
|
|
Term

|
Definition
lateral aspect of the humerus
-Insertion for the deltoid muscle |
|
|
Term
Where is the radial groove?
What is the readial groove? |
|
Definition
posterior and inferior to the deltoid tuberosity
-accomodates the radial nerve and profunda brachii artery
*when you hear radial nerve, think extension* |
|
|
Term

What is the anatomical neck?
What is the Surgical neck? |
|
Definition
-Separates the head of the tubercles
-distal to the tubercles and a junction between the proximal end and the body |
|
|
Term
