Summary
This study introduces a new method for quantifying equine skull morphology in live and deceased horses. The research identified distinct skull differences among Arabian, Thoroughbred, and Standardbred breeds.
Area of Science:
- Veterinary Anatomy
- Comparative Morphology
- Equine Science
Background:
- Quantifying equine skull morphology lacks a standardized, validated methodology.
- Existing methods may not be applicable to live animals or account for soft tissue variations.
Purpose of the Study:
- To develop and validate a novel method for measuring equine skull morphology.
- To assess the applicability of the method to both live and deceased horses.
- To investigate breed-specific variations in equine skull structure.
Main Methods:
- Recorded nine head measurements and six indices from 30 horses of various breeds with intact soft tissues.
- Utilized a specific anatomical landmark (palpable notches caudal to the caudal lacrimal process) to delineate cranial and facial regions.
- Employed statistical analysis to identify correlations between measurements and assess breed differences.
Main Results:
- Demonstrated positive correlations among several equine head measurements.
- Revealed significant differences in skull morphology between Arabian, Thoroughbred, and Standardbred horses.
- The proposed method proved effective for quantifying skull features in intact heads.
Conclusions:
- The developed method offers a reliable approach for equine skull morphology quantification.
- This technique is suitable for diverse equine populations, including live animals.
- The findings highlight the importance of breed-specific considerations in equine skull analysis.

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
