Anatomy Lecture 7

Shoulder Blade

"shoulder socket"

attaches directly to the head of the humerus

the most upper bony process of the scalpula, extends laterally to the shoulder

articulates with the clavicle

the anterior upper bony process of the scapula.

together with the acromion, it stabilizes the shoulder joint.  it is apart of the deltoid and pectoralis major muscles

the posterior upper, smooth part of scapula

it is the origin of the Supraspinatus

the posterior, lower part of the scapula (major smooth surface area)

it is the origin of the Infraspinatus

large surface area that is the DEEP posterior section of the scapula

the origin of the subscapularis muscle

a dome-shaped structure that goes into the shoulder joint and has the articular capsule

the larger bump on the top of humerus (NOT THE HEAD)

Gives insertion to the supraspinatus, infraspinatus and teres minor

on top of humerus and is the smallest bump

insertion of the subscapularis

this is the groove between the greater and lesser tubercles.

it is the insertion of the biceps brachii

on the distal end of humerus, it is the lateral bump

origin of the supinator

at the distal end of the humerus, it is medial and larger than the lateral epicondyle

the ulnar nerve is protected by this... thus the "funny bone" 

origin of the pronator teres

distal end of humerus, it articulates with the head of the radius (so right facet of right arm)

distal end of humerus, it articulates with the head of ulna (left articulation of right arm) 

(part of elbow joint)

from the anatomical position it is medial to the radius

part of forearm (antebrachial)

The actual "elbow bone" 

proximal end of ulna

proximal end of unla

serves as the large depression for the trochlea of the humerus

proximal end of ulna

serves as the depression for the head of the radius

bumpy distal end of ulnar

provides articulation for carpal ligaments and muscles

antebrachial, from the anatomical position it is lateral to the ulna

proximal end of radius

articulates with the capitulum of humerus

a bump on the proximal end of the radius deep in the antebrachial region

serves as an insertion for biceps brachii

lateral bump at distal end of radius, is the insertion of the brachialradialis

bones contained in the wrist

the main and lateral parts of the hip bone

the concave surface of the pelvis where the head of the femur goes

is the hole created by the ischium and pubis bones of the pelvis where nerves and blood vessels pass

the joint between the sacrum and ilium of the pelvis

upper and largest bone of the pelvis. 

it has the iliac crescent (top border)

top front of the iliac bone

provides attachment for the inguinal ligament, and the sartorius muscle

most anterior part of pelvis

forms part of the acetabulum

the joint that unites the left and right pubic bones

most inferior part of pelvis

most inferior part of ischium

the part that you "sit with"

most proximal part of femur, is the part that articulates with pelvis

a proximal part of femur that is the neck of the head

most prominent in elderly

larger bump on proximal end of femur that is NOT the head

insertion of the gluteus medius

proximal end, the smallest bump

medial distal bump of the femur

larger than lateral (more weight bearing)

lateral distal bump of femur

the medial distal bump that is on the side of femur

origin of the gastrocnemius

smaller, distal and on the side of the femur

attaches the fibular collateral ligament

"knee cap"

medial and more weight bearing bone of the leg (vs fibula)

the anteriorly protruding part of tibia

provides attachment to the patellar ligament

the distal lateral bump of tibia

lateral and less weight bearing of the leg bones

proximal end of fibula

distal and lateral bump of fibula

attachment for ankle muscles and tendons

the upper ankle bone

the lower, larger ankle bone
