Unit 1.6 Flashcards
Bones in the shoulder girdle
The clavicle and scapula
The upper extremity
The shoulder girdle and the upper limb
The upper limb is composed of
Humerus, radius, ulna ,canals, metacarpals, and phalanges
The lower extremities
The pelvic girdle, bones of the os coxae, lower limbs
The pelvic girdle is the
Ilium, ischium, and pubis
Known as os coxae
The lower limb is composed of
Femur, tibia, fibula, tarsals, metatarsals, and phalanges
The clavicle is an attachment site for
Known as
One of the components
The girdle attaches the limb to
The girdle also
Features
Muscles of the chest and those that act on the shoulder
Collarbone
Of the pectoral girdle
The axial skeleton, acts to stabilize the shoulder region
Transmits weight (force) from the arm across the thorax and down the axial skeleton
Sternal end, acromial end, costal tuberosity
The scapula is an attachment site for
Known as
One of the components of
Example of
Features
Muscles of the shoulder and those that act on the arm
The shoulder blade
The pectoral girdle
A flat bone
Coracoid process, acromion, glenoid cavity, supraglenoid tubercle, infraglenoid tubercle, subscapular fossa, lateral and medial borders, superior and inferior angles, spine, supraspinous fossa, and infraspinous fossa
The humerus is anatomically in the region termed
Is a
Example of
Features
Brachium
An insertion site for the muscles that act on the shoulder and site of origin for muscles that act on the elbow and digits.
Long bone
Head, anatomical and surgical necks, greater and lesser tubercle, intertubercular sulcus, radial groove, coronoid fossa, radial fossa, deltoid tuberosity, medial and lateral epicondyle, capitulum, trochlea, Olecranon fossa
The radius and ulna are in the anatomical position known as
They are
Example of
Features of radius
Features of ulna
The antebrachium
Are insertion sites for muscles that act on the elbow and site of origin for some of the muscles that act on digits
Long bones
Head, neck, radial tuberosity, ulnar notch, styloid process, interosseous border
Olecrannon process, trochlear notch, coronoid process, radial notch, styloid process, interosseous border
The carpals are in the anatomical region known as the
They are
Number
Examples of
Names
Identified
Carpus
Insertion sited for the muscles that act on the writs and site of origin of the muscles that act on the digits
There are two rose of carpal bones, proximal and distal
Short bones
Proximal (scaphoid, lunate, triquetrum, pisiform) distal (trapezium, trapezoid, capitate, hamate)
Lateral to medial
The metcarpals are in the anatomical region known as the
They are
Examples of
Features
Dorsum and the palmer surfaces of the hand
Insertion sites for muscles that act on the wrist and site of origin for some of the small muscles of the hand
Long bones
Head (condyle = round and distal), shaft (central shaft), base (flat articulation surface and proximal)
The phalanges are
Anatomical term for individual bones of each digit is
Number
Example of
Features
Attachment site for muscles that act on digits
Phalanx
There are 5 proximal phalanges, 4 middle phalanges, and 5 distal phalanges
Long bones
Head, body, base
Homologous of the humerus and femur
Greater and lesser tubercles = humerus
Greater and lesser trochanter = femur
Head and necks
Deltoid tuberosity = humerus
Gluteal tuberosity = femur
Medial and lateral epicondyles
Homologous of the radius/ulna and tibia/fibula
Head and neck of the radius and fibula are both lateral bones from the anatomical position and proximal
Radial tuberosity is similar to tibial tuberosity
Styloid process of radii and ulna are similar to the mallelous of the tibia and fibula and are both distal
Metacarpals= metatarsals
Digits are numbered on the upper limb lateral to medial but the lower limb is medial to lateral
