Answer 1

atlas

Question 2

two small bones that are part of the external bones of the cranium located on the dorsal midline between the occipital bone and the parietal bones. Usually clearly visible in young animals. Older animals- may fuse together into one bone or fuse to the parietal bones and become indistinguishable

Answer 2

interparietal bones

Question 3

two skull bones among the external bones of the cranium that form the dorsolateral walls of the cranium. Large and well developed in dogs, cats, and humans but small in horses and cattle

Answer 3

parietal bones

Question 4

skull bones that are part of the external bones of the cranium. These two bones form the lateral walls of the cranium, contain the middle and inner ear structures, and are the skull bones that form the temporomandibular joints (TMJs) with the mandible (lower jaw). located below/ventral to the parietal bones

Answer 4

temporal bones

Question 5

the bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone. In the living animal, it contains the external ear canal

Answer 5

external acoustic meatus

Question 6

the hinge joint on each side of the mandible that connects it with the rest of the skull. Each joint is formed by the convex condyle of the mandible articulating with the concave articular surface on the ventral portion of each temporal bone

Answer 6

temporomandibular joints (TMJs)

Question 7

skull bones; external bones of the cranium. These two bones make up the “forehead” region of the skull and contain the large frontal sinuses. The cornual process (horn core) in horned animals is an extension of the frontal bone

Answer 7

frontal bones

Question 8

the large paranasal sinus in the frontal bone of the skull

Answer 8

Frontal sinus

Question 9

a skull bone that is one of the internal bones of the cranium. f\Forms the ventral part of the cranium and contains a depression- the pituitary fossa- that houses the pituitary gland.

Answer 9

sphenoid bone

Question 10

a depression in the dorsal surface of the sphenoid bone that houses the pituitary gland in the living animal

Answer 10

pituitary fossa

Question 11

the paranasal sinus in the sphenoid bone

Answer 11

sphenoidal sinus

Question 12

a skull bone; an internal bone of the cranium. This single bone is located just rostral (ahead of) the sphenoid bone. It contains the cribriform plate, which transmits the many branches of the olfactory nerve to the olfactory bulb of the brain

Answer 12

ethmoid bone

Question 13

The sievelike area of the ethmoid bone through which the many branches of the olfactory nerve pass from the upper portion of the nasal cavity to the olfactory bulbs of the brain

Answer 13

Cribriform plate

Question 14

The skull bones that do not surround the brain. The externally visible bones are the incisive, nasal, maxillary, lacrimal, zygomatic, and the mandible bones. Internal are the palatine, ptergoid, voters, and turbinate bones

Answer 14

Bones of the face

Question 15

One of the three ossicles, which are the tiny bones that transmit sound wave vibrations across the middle ear. It is the outermost of the three ossicles and attached to the tympanic membrane

Answer 15

Malleus/hammer

Question 16

Skull bones that are the bones of the ear. Six tiny bones, three on each side, in the middle ear that transmit sound wave vibrations from the tympanic membrane to the inner ear. From outside in they are the malleus, incus, and the stapes

Answer 16

Ossicles

Question 17

One of the three ossicles, the tiny bone that transmit sound wave vibrations across the middle ear. This is the middle of the three ossicles.

Answer 17

Incus/anvil

Question 18

One of the three ossicles which are the tiny bones that transmit sound wave vibrations across the middle ear. This is attached to the membrane that covers the oval window of the cochlea. It is the innermost of the three ossicles

Answer 18

Stapes/stirrup

Question 19

The paper thin connective tissue membrane that is tightly stretched across the opening of the external ear canal into the middle ear

Answer 19

Tympanic membrane/eardrum

Question 20

The snail shell shaped cavity in the temporal bone of the skull that contains the hearing portion of the inner ear. In this cavity, receptor cells for hearing convert the vibrations to nerve impulses that are interpreted by the brain as sound.

Answer 20

Cochlea

Question 21

Skull bones that are part of the external bones of the face. The two incisive bones are the most rostrum of the skull bones. In all common domestic animals, except ruminates, the incisive bones house the upper incisors teeth

Answer 21

Incisive/premaxillary bone

Question 22

Skull bones that are part of the external bones of the face. The nasal bones form the bridge of the nose, or the dorsal part of the nasal cavity

Answer 22

Nasal bone

Question 23

Long faced dog breed where the nasal bones are long and thin

Answer 23

Dolichocephalic

Question 24

Short faced dog breeds where the nasal bones are short and more triangular

Answer 24

Brachycephalic

Question 25

Skull bones; external bones of the face. These two bones make up most of the upper jaw and house the upper canine teeth if present, and all of the upper check teeth (premolars and molars) and the maxillary sinuses

Answer 25

Maxillary bones

Question 26

Skull bones; external bones of the face. These two small bones form part of the medial portion of the orbit of the eye and house the lacrimal sacs, which are part of the tear drainage system of the eye

Answer 26

Lacrimal bones

Question 27

The paranasal sinus in the maxillary bones

Answer 27

Maxillary sinus

Question 28

The bony roof of the mouth; the division between the mouth and the nasal cavity. The soft palate is immediately caudal to this palate. It is made up of portions of the maxillary and palatine bones
