Lecture 4- Superior Appendicular Skeleton Flashcards
Mastery
what makes up the pectoral girdle
what is the joint called
Clavicle
Scapula
Humerus
Glenohumeral Joint
What makes up the wrist
Catch a carp with my hands
carpals
meta carpals
Phalanges
Metacarpophalangeal Joints
Interphalangeal joints
superior view of the Upper limb
where does the clavicle attach
how to know which side the clavicle is
Acromion
Spine of scapula
Clavicle
——The clavicle attaches to the pectoral girdle and articulates with the manubrium
——- Sternal end(articulation), acromial end. Superior in smooth and inferior is rough for muscle attachments
Glenohumeral Joint
Ligaments strengthen the joint
Articular Cavity is filled with synovial fluid to reduce friction
Synovial membrane
articular capsule surrounds the joint
Anatomy of the scapula
- Glenoid Cavity and Supra/infraglenoid tubercle
- Spine of scapula
- Coracoid Process
- Acromion
- Borders
- superior and inferior angle
-suprascapular notch(foramen) - Supra/infraspinous fossa
- Subscapular fossa
Anterior/ posterior view of humerus
-Head
- Intertubercular groove
- radial groove
- Lesser tubercle
- Greater tubercle
- Medial/Lateral epicondyle
- Medial/Lateral Lip
- Floor of the intertubercular groove
- Deltoid Tuberosity
- Olecranon Fossa
- Coronoid Fossa
- Capitulum(Radius)
-Trochlea(ulna)
Radius and Ulna anterior
Radius and Ulna posterior
Radius is more lateral
Ulna is more medial
- — — Styloid processes
———————————–
Head of radius is flat, inferior is larger
has a radial tuberosity
Head of ulna is pointy
- Trochlear notch
- radial notch articulates with head of radius
Ulna- Olecranon(attaches to olecranon fossa and trochlea
Radius- Similar with flat head
Elbow Joints
what accommodates during flexion and extension
Synovial and hinge joint
HUMERORADIAL JOINT
- head of radius articulates with capitulum
HUMEROULNAR JOINT
- Trochlear notch or ulnas articulates with Trochlea
during flexion, the coronoid fossa accommodates the coronoid process of the ulna
during extension, the olcranon fossa on the posterior side makes space for the olecranon of the ulna during extension
Supinate and pronate the forearm
what is between the ulna and radius
pronate is flat
supinate is when radius crosses over ulna——-I carry soup
interosseus membrane is between the two forearm to keep them together
and is an attachment site for muscles
DIGITS of the hand
Phalanges- distal,middle, proximal
Metacarpals
Carpals
Carpals attach to radius
DIP
PIP
I.M.C
- interphalangeal joint - hinge
- Metacarpophalangeal joints— condylar
- Carpometacarpal joint—saddle
Radiocarpal joint- Synovial Joint
BONES of hand
So Long to Pinky
- Scaphoid, Lunate, Triquetrum, Pisiform
Here Comes The Thumb
- Hamate, Capitate,Trapezoid, Trapezium
Superior and Lateral view of humerus
- Lesser and Greater Tubercle
- Superior/Middle/Inferior Facet
- Coracoid
- Acromion
