Anatomy I: Lesson 1

Anatomical Directions and Specie Identification Objective: Students will study the essentials of veterinary anatomy in order differentiate between species, identify variations and explore anatomical directions.

Car – carnivora (meat-eating animals) ca – canis familiaris (dog)

fe – felis catus (cat)

Un – ungulates (hoofed animals) eq – equus caballus (horse)

ru - ruminantia (cattle, goat, sheep) su – sus scrofa domestica (pig)

Phalanx prox., med., dist.

Regions of the Head

- frontalis, parietalis, occipitalis, temporalis, auricularis, oralis etc.

- masseterica - mentalis (chin) - supra- and

infraorbitalis - palpebra inferior - labialis superior - mandibularis

Regio

- mentalis (chin)

- mandibularis

- intermandibularis

- subhyoidea (bone within tounge)

Regio parotidea

Fossa retromandibularis

Vertebrae Anatomy

body (corpus)

◦ extremitas cran. (convex) & caud. (concave) discus intervertebralis, NO synovial joints !

arch (arcus): 2x pediculus + lamina

◦ DORSAL! – orientation

◦ incisura cran. + caud. foramen intervertebrale

(for. vertebrale laterale)

processes (processus)

◦ proc. spinosus, transversus, articularis

◦ proc. mamillaris (+cran. artic.), accessorius

What Aspect?

What Aspect?

Cervical Vertebrae

mobility

body very convex + concave

articular surfaces very large

- proc. transv. tuberculum dors. + ventr.

- for. transversarium? (cervical only)

- ALL SPECIES HAVE 7 CERVICAL VERTEBRA!

Cervical Vertebrae, C1

C1 – atlas, nodding movement ◦ body massa lat., proc. transv. wing (ala atlantis), no proc. articularis, proc. spinosus

tuberculum

◦ cran.: deep excavation for condylus occipitalis

◦ ventral: excavation: fossa alaris

◦ foramina (interspec. diff.)

for. alare fossa alaris

for. vertebrale lat. (MED!) canalis vertebralis

for. transversarium perforates proc. transv.

Cervical Vertebrae

C2 – axis, rotatory movement

cran. projection: dens axis ◦ interspec. diff.: shape of dens

fac. articul. cran.

proc. spinosus

C6 – tuberculum ventr. lamina ventralis

C7 – caud: attachment of 1st rib, NO for. transv.
