ANAT 100 COMPREHENSIVE EXAM 2025/2026 QUESTIONS
AND SOLUTION RATED A+
✔✔There are three additional features of long bones. - ✔✔- Articular Cartilage
- Periosteum
- Medullary
✔✔What type of cartilage is articular cartilage? - ✔✔Hyaline because it lines the joint
surface
✔✔What is the function of the inner cavity of the long bone, or medullary cavity? -
✔✔Blood cell production occurs in the bone marrow within the medullary cavity
✔✔Articular Cartilage- - ✔✔Articular cartilage covers the epiphysis, reduces friction
between joints, and absorbs shock in movable joints.
✔✔Periosteum - ✔✔A tough sheath of dense irregular connective tissue that covers the
surface of bone, except for areas covered by articular cartilage. The periosteum
protects the bone and contains blood vessels and nerves that supply the bone. It also
has cells that are responsible for forming new bone tissue
✔✔Two sets of bones make up the skull: - ✔✔the cranial and facial bones
✔✔FRONTAL BONE - ✔✔- Single bone
- Forms the forehead and roof of the orbits (eye sockets)
✔✔TEMPORAL BONE - ✔✔The temporal bones are paired and form the lateral and
inferior walls of the skull.
Features:
1. Zygomatic process
2. External auditory (acoustic) meatus (ear hole)
3. Mastoid process
✔✔SPHENOID BONE - ✔✔The sphenoid is a single bone. It is known as the "keystone"
of the skull as it joins the cranium and facial bones by attaching with almost every other
bone of the skull.
✔✔What does the shape of the sphenoid bone remind you of? - ✔✔The shape of the
sphenoid bone resembles a bat with its wings extended
✔✔PARIETAL BONES - ✔✔- Paired
- Form superior and lateral surfaces of skull
, ✔✔OCCIPITAL BONE - ✔✔- Single
- Forms posterior wall and the base of the skull
1. Foramen magnum (big hole)
The foramen magnum allows the spinal cord to exit the cranial cavity.
2. Occipital condyles
The occipital condyles articulate with the first bone in the neck
✔✔Coronal: - ✔✔Junction between frontal and parietal bones.
✔✔Sagittal: - ✔✔Junction between parietal bones.
✔✔Lamboid: - ✔✔Junction between the occipital and parietal bones.
✔✔Squamous: - ✔✔Junction between temporal and parietal bones.
✔✔CRANIAL VAULT - ✔✔Recall that the cranial vault refers to the dome-shaped bony
roof of the skull that encases the brain. Itis formed by the frontal, parietal, and occipital
bones which are flat bones. The cranial vault is sometimes called the skullcap.
✔✔CRANIAL BASE - ✔✔A fossa is defined as a depression in a bone. The floor of the
cranium (cranial base), on which the brain sits, contains three fossae:•
- Anterior cranial fossa
- Middle cranial fossa
- Posterior cranial fossa
✔✔MAXILLARY BONES (MAXILLAE) - ✔✔- Paired
- Upper jaw bones
✔✔NASAL BONES - ✔✔- Paired
- Articulate with the frontal bone
- Form bridge of the nose
✔✔ZYGOMATIC BONES - ✔✔- Paired
- Form the cheekbones
A feature of these bones is the temporal process, which articulates with the zygomatic
process of thetemporal bone to form the zygomatic arch
✔✔MANDIBLE - ✔✔- Single
- Forms the lower jaw
You can palpate the angle of your mandible on either side of your face by starting at
your ear lobes and moving your fingers downward.
✔✔VERTEBRAL COLUMN (SPINE) - ✔✔The adult spine is made up of 26 bones:
