ANATOMY Of THE HORSE. 
5 
HYO-EPIGLOTTIDEUS. 
Situation. —Between the epiglottis alid semicircular part of the 
os hyoides. 
Figure .—Fusiform. A single muscle. 
Attachment. —To the hollow part opposite to the neck of the 
os hyoides; and to the broadest part of the epiglottis : en¬ 
veloped within a doubling of the laryngeal membrane, and 
clothed.in[adipose matter. 
Structure. —Pale fleshy fibres, mingled with fatty matter at 
its hyoideal attachment, and fixed to the epiglottis by a very 
small tendon. 
Action. —To retract the epiglottis still further from the aper¬ 
ture, and thus increase the dimensions of the latter. 
10.—PALATINE REGION. 
Including one pair, and a single muscle. 
tensor p a lAt i.— Stylo-staphyleus. 
Situation. —Upon the supero-lateral part of the pharynx. 
Form. —Slender, elongated; tapering towards either extremity. 
Attachment. —Posteriorly, to the styloid process of the tem¬ 
poral bone, by means of a tendon common to it and the stylo- 
pharyngeus : anteriorly, by means of a cartilaginous loop (acting 
as a pulley), through which its tendon passes, to the styloid 
process of the palate bone : and, making a sudden turn outw ard, 
around this process, it becomes ultimately fixed to the postero¬ 
lateral part of the soft palate. 
Direction. —From behind, fonvards. 
Relations .—Inwardly, with the stylo-pharyngeus and palato- 
pharyngeus; outwardly, wdth the pterygoideus interims. 
Structure .—Fleshy, in the middle; aponeurotic, externally: 
terminating, anteriorly, in a long, flat, slender tendon, which 
plays within a cartilaginous pulley. 
Action. —To stretch or dilate the palate. 
circumplexus palati. — Stapkyleus . 
Situation. — Infolded within the velum palati. 
Formi —Collected into fasciculi, posteriorly : broad, thin, and 
expanded, anteriorly. 
Attachment .—Anteriorly, to the semi-oval border formed by 
the union of the palate bones ; posteriorly, to the palate; within 
the substance of which its fibres are intermingled with those of 
the stylo-pharyngeus and tensor palati. 
Structure. —Fleshy, posteriorly ; aponeurotic, anteriorly. A 
single muscle.
