The equine larynx.
Abstract: Abstract Extract A series of landmark studies on the function of the equine larynx was conducted by a group of researchers at Massey University between 1970 and 1987. These studies commenced with investigations on the normal laryngeal anatomy and physiology (Goulden et al 1976a; Anderson et al 1980; Quinlan et al 1982), and progressed to a clinical appraisal of laryngeal hemiplegia, the most important clinical disease affecting the horse's larynx (Goulden and Anderson 198 lab, 1982). The studies concluded with a series of in-depth cytological and pathological studies of the intrinsic laryngeal muscles and nerves in the horse (Cahill and Goulden 1986abcde).

This research article summarizes a series of studies conducted between 1970 and 1987 on the function of the horse’s larynx, by researchers at Massey University. The studies initially focused on understanding normal laryngeal anatomy and physiology, further progressing to diagnosing and treating laryngeal hemiplegia, a major equine laryngeal disease, and concluded with a deep analysis of the intrinsic laryngeal muscles and nerves.
Understanding Normal Laryngeal Anatomy and Physiology
- In the initial stages of the study, the researchers investigated the normal structure and functioning of a horse’s larynx. This included studying the anatomical features, their positions, and their roles in the equine larynx.
- Understanding these basics provided an essential foundation for the following parts of the study, reinforcing an understanding of how deviations from this norm could lead to disease.
Diagnosing and Treating Laryngeal Hemiplegia
- Once the researchers had a firm grasp on the basic anatomy and physiology of the larynx, they moved on to studying laryngeal hemiplegia. This disease is significant as it is the most common laryngeal disorder found in horses.
- The disease involves paralysis of one side of the larynx, leading to difficulties in breathing, insufficient oxygen intake during exercise, and a distinctive roaring noise when the horse inhales.
- This part of the study included clinical appraisals to accurately diagnose and treat this disease, aiming to improve overall equine health.
In-depth Cytological and Pathological Studies of the Intrinsic Laryngeal Muscles and Nerves
- In the final part of their study, the scientists conducted comprehensive cytological and pathological examinations of the intrinsic laryngeal muscles and nerves in horses.
- Cytological studies involve an analysis of cells and their functions while pathological studies evaluate the organs and tissues to examine the effects of diseases.
- These studies allowed for a deeper understanding of the diseases affecting the equine larynx, helping to inform future research and treatment options.
