Lab Chapter 7 The Axial Skeleton Flashcards
Sutures ____ immovable connections
between most cranial bones
Lambdoid Suture: Arches across inferior posterior cranial,
connects the Parietal bones to the Occipital bone
The Coronal Suture:
attaches the Frontal to the Parietal bone
The Sagittal Suture:
from Lambdoid to the Coronal, between the Parietal bones
Occipital bone _____
is Posterior inferior of the cranial
Foramin Magnum : connects cranial cavity to _____
the vertebral canal
Foramin Magnum surrounds the connection between the brain ____ spinal cord
And
The 4 Sutures _____:
Lambdoid, Coronal, Sagittal and Squamous
The Cranium bones are:
Occipital, 2 Parietal bones, Frontal bone, 2 Temporal bones, Sphenoid ____ Ethmoid bone
Frontal bone contains ____
the Frontal Sinus
The Auditory Ossicles are
within the Temporal bone
Test - Zygomatic Arch: formed ____
by the Temporal Process and Zygomatic Process
7 bones form _____ Orbital Complex
the
Nasal Complex includes:
Nasal Cavity and Paranasal Sinus
Fontanelles: Non Ossified fibers that
allow rapid brain growth in infants + children
4 Vertebral Column flexible Spinal Curves:
Cervical, Thoracic, Lumbar and Sacrum-Coccyx
Sacrum and Coccyx ____
are fused
Skull has
8 Cranial, 14 Facial and 6 Auditory / 1 Hyoid bone (associated bones)
Mastoid and Styloid Process: muscle attatchment processes
Thoracic Cage: Vertebrae are
heart shaped, 24 ribs and 1 Sternum
Thoracic Cage: Sternum, 24 Ribs, 12 each side and _____
1-7 are True Ribs, 8-12 are false ribs, 11-12 float
Typical Rib:
head, neck, tubercle and body
Spinal ailments: Kyphosis, Lordosis and Scoliosis
Scoliosis can be repaired.. caused by poor posture
Axial Skeleton has 80 bones, in the
head and trunk, 40% of bodies bones.
Mastoid Process, Styloid Process is
muscle attachment
Male skull has a very pronounced
Occipital Process
8 Cranial Bones Are
frontal, parietal, 2 temporal, occipital, sphenoid, and ethmoid bones
8 facial bones are
Maxillae (upper oral) Palatine, Nasal (nose attached to Maxillae, Zygomatic, Volmer, Mandible, Inferior Nasal and Lacrimal (behind nasal)
Test - Zygomatic Arch Processes and Temperal Process
Test - Cranial Sutures Lamboid - arches across posterior of the skull, Connects Occipital with Parietal bones
Coronal Suture - attaches the Frontal to the Parietal bone, The Sagittal Suture goes between the Lamboid to the Coronal
Foramina - Connects Cranial to Vertebral Canal.’
surrounds the connect between brain and spinal column
Occipital Bone - External Portubance Bump (male is larger), External Occipital (Point were ligaments attach)
and Occipital Condytes (sites of articulation)
Fontanelle are
Cranial Softs spots, non ossified fibers that allow rapid brain growth in infants and children
Frontal Bone - Forehead
Provides surface area for muscle attachments
Vertebrosternal Ribs are true ribs
Vertebrochondral = False Ribs , The Vertebral Ribs are - Floating Ribs
Spinal Column - Cervical (Secondary Curve)
Thoracic (Primary Curve) and Lumbar (Secondary Curve).
Cervical C1 and C2 Axis and Atlas vertabrae allow articulation of the head.
Thoracic Cage Consists of 25 bones
Vertabrae (24 C1-7, T 1-12, L 1-5) and Sacrum and Coccyx
Sternum is the
Jugular Notch at top, the Maniubrum , body and Xyphoid process
Axial Skeleton 80 Bones
29 Cranial, 25 Thoracic and 26 Vertebrae Column.
Sacral bones: Fused together, 8 Foramina, Top is the Base,
Vertebrae: large Spinus process, Vertebral body, Traverse Process
Superior and Inferior Articular Processes, Vertebral Foramen (hole for spinal nerves)
