What is the relationship of the cervical vertebrae to the dorsal midline?
Gently sloping backwards "s" curve
What are the anatomical differences of the nuchal ligament in the horse and the dog?
Dog (1 component) - from spine of T1 to spine of axis
Horse (2 components) - funiculus nuchae (cord-like) from skull to spines of thoracic vertebrae of withers where it becomes continuous w/supraspinous ligament; lamina nuchae (sheet-like) from spines of T2-3 to spines of C2-6
Where are the bursae located in relation to the nuchal and supraspinous ligaments?
Cranial nuchal bursae - between the arch of the atlas (C1) and the funiculus nuchae
Caudal nuchal bursae - between the spine of the atlas (C2) and the funiculus nuchae
Supraspinous bursa - over the whithers at the junction of the funiculus nuchae cranially and the supraspinous ligament caudally
What clinical conditions involve these bursae?
Poll evil - inflammation/infection of cranial nuchal bursa
Fistulous withers - inflammation/infection of the supraspinous bursa
What condition affects the cervical vertebrae causing compression of the spinal cord and ataxia in horses?
Where is the crest? What is the composition of the tissue in this area?
Located on the dorsal midline of the neck; composed of fat
Identify the topographic position of the wing of the atlas
Can be palpated near the base of the poll
Identify the superficial muscles of the ventral surface of the neck
