Lab: Appendicular Skeleton Flashcards
How many bones make up the appendicular skeleton?
126
Function to attach the upper limbs to the axial skeleton, and provide attachment points for many trunk and neck muscles. Consist of the anterior clavicle and the posterior scapula
Pectoral, or shoulder, girdles
A slender doubly curved bone; aka the collarbone
Clavicle
Part of the clavicle; Attaches to the sternal manubrium; is rounded or triangular in cross section.
Sternal (medial) end
Part of the clavicle; flattened where it articulates with the scapula to form part of the shoulder joint
Acromial (lateral) end
Part of the clavicle on the acromial end that anchors a ligament and provides a handy landmark for determining whether a given clavicle is from the right or left side of the body
Conoid tubercle
Generally triangular; “wings” of humans; aka shoulder blades
Scapulae
The enlarged roughened end of the spine of the scapula
Acromion
Beaklike process of the scapula; means crow, raven
Coracoid process
At the base of the coracoid process allows nerves to pass
Suprascapular notch
Long bone of the arm
Humerus
Two prominences opposite of the head, separated by a groove that guides the tendons of the bicep muscle to its point of attachment
Greater and lesser tubercles
Roughened area in the middle of the humerus shaft where the deltoid attaches
Deltoid tuberosity
A condyle at the distal end of the humerus; looks like a spool and articulates with the ulna
Trochlea
A condyle at the distal end of the humerus; articulates with the radius
Capitulum
The funny bone
Medial epicondyle
Above the trochlea; two depressions that allow the corresponding processes of the ulna to move freely when the elbow is flexed and extended
Coronoid fossa and olecranon fossa
Lateral bone of the forearm
Radius
Point of attachment for the tendon of the biceps muscle of the arm
Radial tuberosity
Where the radius articulates with the end of the ulna
Ulnar notch
The medial bone of the forearm
Ulna
Two processes that grip the trochlea of the humerus in a plierslike joint
Coronoid and olecranon process
Lateral side of the coronoid process that articulates with the head of the radius
Radial notch
Serves as a point of attachment for ligaments of the wrist on the ulnar head
Styloid process
Name the 8 carpals
Scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate, hamate
2 coxal bones (aka ossa coxae, or hip bones) form the
Pelvic girdle or hip girdle
Large flaring bone of the coxal bone
Ilium
The rough, superior margin of the iliac bone
Iliac crest
Where the iliac crest terminates anteriorly and posteriorly
Anterior/posterior superior spine
The “sit-down” bone, forming the most inferior and posterior portion of the coxal bone
Ischium
Receives the weight of the body when sitting
Ischial tuberosity
Allow nerves and blood vessels to pass to and from the thigh
Lesser and greater sciatic notches
The most anterior portion of the coxal bone
Pubis, or pubic bone
Where blood vessels and nerves run from the pelvic cavity into the thigh
Obturator foramen
Means “wine cup” where the ilium, ischium, and pubis fuse and receives the head of the thigh bone
Acetabulum
Thigh bone
Femur
Small central pit in the femurs head
Fovea capitis
Articulates with the tibia; where the femur terminates distally
Lateral and medial condyles
Forms a joint with the patella anteriorly
Patellar surface
The shinbone
Tibia
At the proximal end of the tibia; receive the distal end of the femur to form the knee joint
Medial and lateral condyles
A roughened protrusion on the anterior tibial surface and is the site of attachment of the patellar ligament
Tibial tuberosity
Forms the inner bulge of the ankle and articulates with the talus bone of the foot
Medial malleolus
Parallel to the tibia; takes no part in forming the knee joint
Fibula
Forms the outer part, or lateral bulge, of the ankle
Lateral malleolus
How many tarsal in the foot?
7
How many metatarsals?
5
Phalanges?
14
Heel bone; one of the largest tarsals
Calcaneus
One of the largest tarsals that lies between the tibia and calcaneus
Talus
