Practical 1- The Pectoral Girdle And Shoulder Flashcards
what is the pectoral girdle made up of
clavicle and scapula
what is a synovial joint
Joints that contain an articular capsule surrounding a joint between two bones filled with synovial fluid
- the articulating surfaces of the bone are covered by a thin layer of articular cartilage
function of a synovial joint
allows for smooth movement between the adjacent bones eg, knee
Name of the fossa on anterior surface of scapula
sunscapular fossa
name of the fossa on the posterior surface of the scapula above the scapular spine
supraspinous fossa
name of the fossa on the posterior surface of the scapula under the scapular spine
infraspinous fossa
name of the process on the anterior aspect of the scapula
corocoid process
name of the process on the posterior aspect of the scapula
acromoin
what does the head of the humerus articulate with to form the glenohumeral joint
gelnoid fossa of the scapula
where is the greater tubercle
found on the lateral part of the humerus
where is the lesser tubercle
on the anterior part of the humerus
where is the deltoid tuberosity found
on the lateral aspect of the humerus (halfway down ish)
which fossa is found on the distal anterior part of the humerus
coronoid fossa
is the capitulum of the humerus found:
- laterally or medially
- ant or post
lateral
anterior
where is the olecranon fossa found
proximal posterior part of the humerus
which is more prone to fracture: surgical or anatomical neck of the humerus
surgical neck (below the greater and lesser tubercles, horizontal)
origin of pec major
- medial part of clavicle
- sternum
- upper 6 costal cartilages
name of indentation between the lesser and greater tubercles of the proximal anterior part of the humerus.
bicipital groove or intertubucular sulcus
insertion of pec major
- lateral lip of bicipital groove
action of pec major
arm adduction
medical rotation
draws scapula anteroinferiorly
pec minor origin
3rd, 4th, 5th ribs near their costal cartilages
insertion of pec minor
corocoid process of scapula
action of the pec minor
- draws scapula down n forward
- if insertion is fixed, can elevate the 3rd, 4th, 5th ribs
origin of serratus anterior
upper 8 ribs
