SKELETAL SYSTEM OF A CAT Flashcards
The skeleton of the cat is bony except for the __________________________ making up the sterna
COASTAL CARTILAGES
TRUE OR FALSE: Sterna is made up of bones.
FALSE, they are made up of coastal cartilages
Component of axial skeleton
SKULL
HYOID APPARATUS
MANDIBLE
VERTEBRAL COLUMN
RIBS
STERNUM
It exhibits numerous sutures that are sites of articulation between adjacent bones and aid in demarcating their boundaries.
SKULL
A pair of bones forming the lower boundary of the external nares. Each bone bears three small incisor teeth.
PREMAXILLARY BONES
Long pointed bone located posterior to each external nares.
NASAL BONES
Each of these two bones lies lateral to a nasal bone and bears five teeth.
MAXILLARY BONES
They make up the greater part of the upper jaw and palate.
MAXILLARY BONES
A pair of large bones forming the anterior part of the skull and a large portion of the medial wall of each orbit.
FRONTAL BONES
Each frontal bones has a laterally projecting
POST-ORBITAL PROCESS
Each of these two bones bounds the orbit laterally and forms a part of the zygomatic arch
MALAR (JUGAL) BONES
Each __________________ has a post-orbital process that extends upward toward the postorbital process of the frontal bone on that side and a ventrocaudally directed zygomatic process.
MALAR BONE
PAIR OF BONES LOCATED IN THE POSTEROLATERAL REGION OF THE SKULL
PARIETAL BONES
Each articulates anteriorly with a frontal bone and meet its mate in the mid-dorsal line.
PARIETAL BONES
A single median triangular bone located between the posterior parts of the two parietal bones.
INTERPARIETAL BONES
These large flat bones are located, one on each side of the skull, ventral to the parietal bones.
SQUAMOSAL BONES
Temporal bones
SQUAMOSAL BONE, TYMPANIC AND PETROUS
Squamosal gives rise to a
ZYGOMATIC PROCESS
part of the occipital bone located posterior to the parietals
SUPRAOCCIPITAL BONE
Anterior of the two large cavities formed between the frontal bone and the zygomatic arch
ORBIT
The posterior of the two cavities. It is partially separated from the orbit by the post orbital processes of the malar and frontal bones.
TEMPORAL FENESTRAE
Small bone on each side that makes up the anteromedial wall of the orbit.
LACRIMAL BONES
Each of these two small bones is a part of the ethmoid. It lies between the lacrimal and frontal bones
PLANUM BONES
A transverse crest extending across the upper part of the occipital bone.
LAMBOIDAL RIDGE
A midline ridge that extends vertically along the interparietal and supraoccipital bone.
SAGITTAL CREST
Thin-walled rounded eminence located ventral to the squamosal. It is the tympanic part of the temporal bone.
TYMPANIC BULLA
Outer region of the petrous portion of the temporal bone. Somewhat triangular and projects antero-ventrally adjacent to the tympanic bulla, terminating just posterior to its opening.
MASTOID BONE
VENTRAL TIP OF THE MASTOID
MASTOID PROCESS
The teeth of the cat is made up of
three incisors, one canine, 3 premolars, and one molar
each bone of this pair lies behind the maxillary and along with part of the maxillary, forms the hard plate, which makes up most of the roof of the mouth.
PALATINE BONES
UNPAIRED BONE THAT FORMS THE POSTERIOR PART OF THE NASAL SEPTUM AND THE ROOF OF THE POSTERIOR PART OF THE NASAL CAVITY.
VOMER
A SMALL ELONGATED BONE THAT LIES ON THE MIDLINE BEHIND THE VOMER, AND FORMS PART OF THE ROOF OF THE PHARYNX.
PRESPHENOID BONE
PROCESS OF THE PRESPHENOID BONE, WHICH CAN BE SEEN IN THE POSTEROMEDIAL WALL OF THE ORBIT.
ORBITOSPHENOID BONE
UNPAIRED MIDLINE BONE LYING BEHIND PRESPHENOID
BASISPHENOID BONE
WING-LIKE PART OF THE SPHENOID BONE LOCATED ON THE MEDIAL WALL OF THE TEMPORAL FOSSA
ALISPHENOID BONE
TRANSVERSE DEPRESSION LATERAL TO THE ALISPHENOID. IT IS THE CONCAVITY ON THE MEDIAL SURFACE OF THE ZYGOMATIC PROCESS
MANDIBULAR FOSSA
BROAD UNPAIRED BONE THAT IS PRESENT ALONG THE MIDLINE AND EXTENDS FROM THE BASISPHENOID TO THE FORAMEN MAGNUM
BASIOCCIPITAL BONE
PART OF THE OCCIPITAL BONE; EXTENDS MEDIALLY TO FORM THE ANTEROLATERAL BOUNDARY OF THE FORAMEN MAGNUM
EXOCCIPITAL BONE
ovoid prominence that articulates with the atlas or first cervical vertebra
OCCIPITAL CONDYLE
LARGE BONE OCCUPYING NASAL CAVITY
ETHMOID BONES
A SERIES OF SCROLL-SHAPED BONES IN ETHMOID BONES, WHICH ARE ON EACH SIDE
ETHMOTURBINALS
MEDIAL UNPAIRED VERTICAL PLATE THAT FORMS PART OF THE NASAL SEPTUM
MESETHMOID
WHAT SEPARATES THE NASAL AND CRANIAL CAVITIES?
HORIZONTAL CRIBRIFORM PLATE
A SHELF BONE PROJECTING INTO THE CRANIAL CAVITY; IT PARTILLY SEPARATES THE CEREBRAL AND CEREBELLAR FOSSAE.
TENTORIUM
DEPRESSION IN THE BASISPHENOID BONE THAT HOUSES THE PITUITARY GLAND
HYPOPHYSEAL FOSSA
BONY FLOOR OF THE FOSSA
SELLA TURCICA
THE CAVITY WITHIN THE BASISPHENOID LOCATED ANTERIOR TO THE HYPOPHYSEAL FOSSA
SPHENOID SINUS
CAVITY WITHIN EACH FRONTAL BONE
FRONTAL SINUS
