29
Q

Irregular (shape of bone)

A

Bones that are not long, short, or flat

30
Q

Sutural (shape of bone)

A

Are found within a suture (Articulation between flat bones of the skull)

31
Q

Sesamoid (shape of bone)

A

Are found within a tendon (the only sesamoid bone every person has is the patellae or the kneecap, some sesamoid bones are unique to an individual and can form in other joint such as the wrist, thumb, or ankle.)

32
Q

Axial Skeleton

A

Forms the longitudinal axis of the body, the skull is part of the axial skeleton; Functions of the axial skeleton are to support and protect organs in body cavities, attaches to muscles of head, neck, and trunk, performs respiratory movements, and stabilizes parts of the appendicular skeleton

33
Q

Appendicular Skeleton

A

Forms the arms and legs

34
Q

Clavaria

A

The superior part of the cranial cavity; made up of the occipital, 2 parietal, and the frontal bone.

35
Q

Sagittal suture

A

Suture that divides the parietal bones

36
Q

Coronal Suture

A

Suture that divides the Frontal bone from the parietal bones

37
Q

Lambdoidal Suture

A

Suture that divides the Parietal bones from the Occipital bone

38
Q

Boney nasal septum

A

Medial suture that separates the right and left chambers of the nasal cavity

39
Q

2 Parts of the Boney Nasal Septum

A

Perpendicular plate of the Ethmoid and the Vomer

40
Q

Nasal conchae

A

Lateral sutures that are scroll shaped that the nasal mucosa is attached too. Increase surface area of the nasal mucose that humidifies inhaled air

41
Q

Frontal bone (Eye socket)

A

Superior Wall (roof)

42
Q

Maxilla (eye socket)

A

Floor

43
Q

Zygomatic (eye socket)

A

Lateral wall

44
Q

Sphenoid (eye socket)

A

Posterior wall

45
Q

Ethmoid (eye socket)

A

Posterior medial wall

46
Q

Lacrimal (eye socket)

A

Anterior medial wall

47
Q

Palatine (eye socket) Also in the back of the eye socket

A
48
Q

Zygomatic arch

A

lateral on the skull and made up of 2 parts of 2 bones; the zygomatic process of the temporal bone and the temporal process of the zygomatic bone

49
Q

Mastoid process

A

Posterior and inferior to the external acoustic meatus; Posterior and lateral to the styloid process

50
Q

External acoustic meatus

A

Superior and anterior to the mastoid process; lateral and superior to the styloid process

51
Q

Styloid process

A

Think of a stylus pen, thin and pointy; anterior and medial to the mastoid process; inferior and medial to the externa acoustic meatus

52
Q

Squamous part of the temporal bone

A

Superior flat part of the temporal bone; squamosal sutur is named after this region

53
Q

Mental protuberance

A

A ridge at the most anterior medial edge of the mandible

54
Q

Anterior nasal spine

A

Pointy projection at the inferior medial edge of the nasal cavity

55
Q

Alveolar Processes

A

These are the bumps that are created by the teeth sockets

56
Q

Supraorbital Foramen

A

Hole superior to the eye socket, does not always form a complete hole, when this is the case it is somethings called the supraorbital notch

57
Q

Infraorbital Foramen

A

Inferior hole to the eye socket

58
Q

Mental Foramen

A

Holes found in the mental region, lateral to the mental protuberance

59
Q

Supraorbital notch

A

Superior to the eye socket

60
Q

Optic foramen or canal

A

Round hole through the sphenoid; Passageway for the optic nerve that innervates the eye

61
Q

Superior orbital fissure

A

Oblique hole through the sphenoid bone; passageway for many cranial nerves

62
Q

Inferior orbital fissure

A

One elongated hole between the sphenoid and the maxilla

63
Q

Lacrimal foramen

A

Round hole through the lacrimal bone into the nasal cavity; when you cry your nose does not run, you cry out your nose through the nasolacrimal duct

64
Q

Foramen Magnum

A

Largest foramen in the skull

65
Q

Incisive foramen (anterior palatine foramen)

A

Directly posterior to the incisor teeth

66
Q

Greater palatine foramen

A

These two foramen are just lateral to the posterior palatine of the palatine bone

67
Q
