8Bones Flashcards
Lower jaw bone; contains lower teeth; forms chin; the M in TMJ
Mandible
Articulates with the temporal bone to form a freely movable joint
Mandible
Opening in the temporal bone for the ear
External Auditory Meatus
Upper jaw bone; contains upper teeth
Maxilla
Cheekbones; forms part of the orbits of the eyes
Zygomatic Bones
Forms top and sides of the skull
Parietal
Forms bony structure of the nasal cavity
Ethmoid
Forms the floor and back wall of the cranium; the condyles of this bone sit on the atlas
Occipital
The large hole in this bone is called the foramen magnum
Occipital
Forms the posterior part of the hard palate and the floor of the nasal cavity
Palatine bones
Butterfly-shaped bone that forms part of the floor and the sides of the cranium; the sella turcica houses the pituitary gland
Sphenoid
Forms forehead; articulates with the parietal bones at the coronal suture
Frontal
Means “little fountain” the baby’s soft spots
Fontanels
On the sides of the head close to the ears; the T in TMJ; contains external auditory meatus, styloid process, zygomatic process, and mastoid process
Temporal
First seven pairs of ribs; closest to clavicle; attach directly to sternum by the costal cartilage
True ribs
Next 5 pairs of ribs; ribs that attach indirectly to the sternum
False ribs
Last 2 pairs of false ribs; ribs that do not attach to the sternum
Floating ribs
Lower tip of the sternum
Xiphoid process
The depression on the superior border of the manubrium
Suprasternal notch
The part of the sternum closest to the collarbone
Manubrium
The largest part of the sternum; located between manubrium and the xiphoid process
Body
The articulation between the manubrium and the body of the breastbone; rib 2 located at this articulation; angle of Louis
Manubriosternal joint
Should be less than 90 degrees
Costal angle
Shoulder blade or wingbone; Bone that contains the glenoid cavity; contains acromion and coracoid process
Scapula
Depression where the head of the humerus articulates with the scapula
Glenoid Cavity
Long bone of the arm that articulates with the scapula; the ulna and this bone articulate ti forma hinge joint at the elbow
Humerus
The scapula articulates with this bone to form a ball and socket joint at the shoulder; bone that contains the olecranon fossa
Humerus
Bony part of the ulna that forms the elbow
Olecranon Process
Collarbone; long slender bone that articulates with both the sternum and the scapula
Clavicle
Bones that form palm of the hand; bones that articulate with the proximal phalanges
Metacarpals
The 14 bones that form the fingers
Phalanges
The clavicle and the scapula form this structure; shoulder girdle
Pectoral girdle
Long bone in the forearm that is located on the same side as the pinky; “sidekick” of radius; the radius and this bone cross during supination
Ulna
Wrist bones
Carpals
Bone in forearm that is on the thumb side; contains olecranon process
Radius
Process on the scapula that is the pointy part of the shoulder
Acromion Process
The phalange that contains only 2 bones; the thumb
Pollex
The part of the coxal bone on which you sit
Ischial tuberosity
Bone that contains the obturator foramen; composed of the pubis, ischium, and illium
Coxal bone
Kneecap
Patella
Shin bone; the distal end of this bone is the medial malleolus; the long weight-bearing bone of the leg
Tibia
Cartilaginous disc between the two pubic bones; the disk expands during pregnancy
Symphysis Pubis
Part of the hipbone that “flares”
Ilium
The instep of the foot is formed by these bones; forms the ball of the foot
Metatarsals
Thin, non-weight-bearing long bone of the leg; distal end of this bone is the lateral malleolus
Fibula
Heel bone
Calcaneous
Bony process on the femur
Trochanter
Articulates with the coxal bone to form the hip and the tibia to form the knee; largest bone in the body; thigh bone
Femur
The head of the femur articulates with this depression in the coxal bone; the depression is formed by the union of the ilium, ischium, and pubis
Acetabulum
Formed by the 2 coxal bones and cartilage disk
Pelvic girdle
The big toe; 2 bone phalange
Hallux
This tarsal bone articulates with both the tibia and fibula
Talus
C1; yes motion
Atlas
C2; no motion; dens (odontoid process)
Axis
