17
Q

What is a Facet?

A

A Flat, Articular Surface.

18
Q

What is a Foramen?

A

A Hole in a Bone. Something Important (Nerve or Blood Vessel) Usually Passes Through the Foramen.

19
Q

What is a Fossa?

A

A Depressed or Sunken Area on the Surface of a Bone. Usually Occupied by Muscles or Tendons.

20
Q

What is the Axial Skeleton?

A

The Bones of the Head and Trunk are Located on the Central Axis of the Body.

21
Q

What is the Appendicular Skeleton?

A

The Limbs are Appendages of the Trunk.

22
Q

What is the Visceral Skeleton?

A

Bones Formed in the Viscera, or Soft Organs for Some Animals.

23
Q

What is the Occipital Bone?

A

A Single Bone that Forms the Caudoventral Portion or the Base of the Skull.

24
Q

What is the Foramen Magnum?

A

A Large Hole in the Center of the Occipital Bone. This is Where the Spinal Cord Exits the Skull.

25
Q

What is the Interparietal Bone?

A

Two Small Bones On the Dorsal Midline Between the Occipital Bone and the Parietal Bone. Clearly Visible in Young Animals.

26
Q

What is the Parietal Bone?

A

They Form the Dorsolateral Walls of the Cranium. Well-Developed in Dogs, Cats, and Humans.

27
Q

What is the Temporal Bone?

A

Two Bones Located Below or Ventral to the Parietal Bones. Form the Lateral Walls of the Cranium, they Contain the Middle and the Inner Ear Structures.

28
Q

What are the Palatine Bones?

A

Two Bones that Make Up the Caudal Portion of the Hard Palate, Which Separates the Mouth from the Nasal Cavity.

29
Q

What are Turbinates?

A

Nasal Conchae, Four Thin, Scroll-like Bones that Filter the Air.

Q

What is the Hyoid Apparatus?

A

Also Called the Hyoid Bone, is Located just Above the Larynx. It Supports the Base of the Tongue, the Pharynx, and the Larynx. It Helps the Animal Swallow.
