2. Which bone is the most posterior part of the cranium and base of the skull?

Femur: thigh bone

Palatine: anterior/hard palate

Mandible: lower jaw; lgst., strongest bone. It's body anchors lower teeth. Site of Mental Foramen

Scapula: shoulder blade

Palatine:anterior/hard palate

Occipital: most posterior part of cranium/base skull

The occipital bone is located at the back of the head and forms the base of the skull, supporting the weight of the brain. It also houses the foramen magnum through which the spinal cord passes.

The occipital bone is located at the back of the head and forms the base of the skull, supporting the weight of the brain. It also houses the foramen magnum through which the spinal cord passes.

3. Which bone is described as cocks comb, crista galli, and secures the brain within the skull?

Temporal

Ethmoid: cocks comb, crista galli / secure brain w/in skull upward projects. Most deeply situated bone.

Cribiform plate:olifactory nerves pass through here/Sup, Medial nasal conchae formed from its projections

Frontal

Occipital

The Ethmoid bone is uniquely shaped like a cocks comb and contains the crista galli. It plays a crucial role in securing the brain within the skull.

Explanation

The Ethmoid bone is uniquely shaped like a cocks comb and contains the crista galli. It plays a crucial role in securing the brain within the skull.

4. Which of the following is NOT a part of the temporal bone?

Mastoid process

Squamous

Temporal:4 parts
Squamous(against parietals), tympanic(ear opening), mastoid process (posterior to ear), petrous (lat. portion of skull base). Styloid Process

Tympanic

The temporal bone consists of four parts: squamous (against parietals), tympanic (ear opening), mastoid process (posterior to ear), and petrous (lat. portion of skull base). The inferior nasal concha is actually located on the lateral wall of the nasal cavity.

Explanation

5. How many bones are in the cranium and what are they?

Fibula: calf bone

Femur: thigh bone

Humerus: upper arm bone

Maxilla: upper jaw;soft palate, orbits, nasal cavity walls/alveoli bearing teeth.

Nasal Cavity: site of cribriform plate of ethmoid;

The cranium consists of 8 bones including the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. The Maxilla and Nasal Cavity are not part of the cranium bone structure.

Explanation

The cranium consists of 8 bones including the frontal, parietal, temporal, occipital, sphenoid, and ethmoid bones. The Maxilla and Nasal Cavity are not part of the cranium bone structure.

6. Lacrimal: medial walls of orbit/in front of ethmoidPalatine: L-shaped/posterior hard palate

Temporal: forms part of the cranium;contains auditory ossiclesMandible: lower jaw bone; only moving skull boneVomer: nasal septum; forms part of inferior nasal cavity

Lacrimal: medial walls of orbit/in front of ethmoid

Palatine: L-shaped/posterior hard palate.

The correct answer provides the location and function of Lacrimal and Palatine bones, while the incorrect answers describe other cranial bones and their functions.

Explanation

The correct answer provides the location and function of Lacrimal and Palatine bones, while the incorrect answers describe other cranial bones and their functions.

7. What is the function of sutures in the skull?

Foramen Magnum: An opening at the base of the skull for the spinal cord

Occipital: its condyles articulate with the Atlas of the spine and Foramen Magnum

Suture: Interlocking joints of the skull bones

Suture: A type of musculoskeletal injury

Sutures are the interlocking joints between skull bones that allow for movement during birth and growth, as well as providing stability and protection to the brain.

Explanation

Sutures are the interlocking joints between skull bones that allow for movement during birth and growth, as well as providing stability and protection to the brain.
