Acknowledgement Here are some flash cards all set up in a "pdf" format for you! Thanks to Laura H. (spring 08) for her donation to all my anatomy students! t Here is her suggestion for making flashcards from them: You print out 2 to 11, (there are 2 slides per page). Then you flip the stack and put them back in the printer and print 12 to 21 and they should come out front and back. Then you cut them out. Kinko s has fast paper cutters one can use. It helps if you use card stock. Good luck! lab 7 lab 7 1
Some Lovers Try Positions That They Can't Handle 1. carpals - capitate T L P H S C T 2. carpals - hamate 2
3. carpals - lunate 4. carpals - pisiform 3
5. carpals - scaphoid 6. carpals - trapezium 4
7. carpals - trapezoid 8. carpals - triquetral (triangular) 5
9. humerus (landmarks) - Greater tuberosity bicipital groove Greater tuberosity Lesser tuberosity The bicipital groove is also known as the intertubercular groove or at the proximal end the intertubercular sulcus. It is of functional importance because a tendon from the biceps brachii is guided by this groove to it's origin at the supraglenoid tubercle. Left humerus. Posterior view Left humerus. Anterior view. 10.humerus (landmarks) - capitulum The capitulum (translated this means little head) is also known as the lateral condyle of the humerus. It is an important landmark because it is the articulating surface for the humerus of the humeroradial joint. It articulates with the head of the radius. This is an unusual gliding joint (biaxial) in that it allows for flexion/extension of the forearm and rotation to provide for supination and pronation of the hand. Dr. J recommends that you call it the capitulum because then the little head of the humerus articulates with the head of the radius making it a Grant thing. 6
11. humerus (landmarks) - deltoid tuberosity The deltoid tuberosity of the humerus is of functional importance because it is the insertion for: 1. deltoid and as you have probably guessed, this is another Grant thing! 12.humerus (landmarks) - greater tubercle Three of the four rotator cuff muscles insert on the greater tubercle of the humerus. They are: 1. supraspinatus (superior facet), 2. infraspinatus (posterior aspect), 3. teres minor (inferior facet on posterior surface). 7
13.humerus (landmarks) - head The head of the humerus is the articulating surface for the humerus of the glenohumeral joint that articulates with the glenoid cavity of the scapula. This is a ball and socket joint (triaxial) in that it allows for flexion/extension, abduction/adduction (and circumduction) and rotation of the arm. 14. humerus (landmarks) - lateral epicondyle The lateral epicondyle of the humerus is the origin for: 1. extensor carpi radialis brevis, 2. extensor carpi radialis longus, 3. extensor carpi ulnaris (one head), 4. extensor digitorum communis, 5. anconeus (posterior surface). 8
15. humerus (landmarks) - lesser tubercle The lesser tubercle of the humerus is the insertion for: 1. subscapularis, 2. teres major. 16. humerus (landmarks) - medial epicondyle The medial epicondyle is the origin for: 1. one head of pronator teres, 2. flexor carpi radialis, 3. one head of flexor digitorum superficialis, 4. one head of flexor carpi ulnaris, 5. palmaris longus. 9
17. humerus (landmarks) - olecranon fossa The olecranon fossa is a depression on the posterior side of the humerus at the distal end. It receives the olecranon of the ulna when the forearm is extended. 18.humerus (landmarks) - supracondyloid foramen The supracondyloid foramen is found on the humerus of the cat but NOT on the humerus of a human. The brachial artery and median nerve of the cat pass through this structure and are, therefore, somewhat protected by this arch of bone. 10
19.humerus (landmarks) - trochlea The trochlea is an important landmark of the humerus because it is the articulating surface for the humerus of the humeroulnar joint that articulates with the trochlear notch of the ulna. This is a hinge joint allowing for flexion/extension. Some refer to the trochlea as the medial condyle. Dr. J recommends that you call it the trochlea as it articulates with the trochlear notch, which makes it a Grant thing. 20. metacarpals The second metacarpal is the insertion for: 1. extensor carpi radialis longus (posterior surface of base of the second metacarpal). 2. flexor carpi radialis (base of the second metacarpal). The third metacarpal is the insertion for: 1. extensor carpi radialis brevis (base of the third metacarpal). 2. flexor carpi radialis (base of the third metacarpal). The fifth metacarpal is the insertion for: 1. extensor carpi ulnaris (posterior surface of base of the fifth metacarpal). 11
