The equine neck and its function during movement and locomotion.

Area of Science:

• Equine biomechanics
• Animal physiology
• Veterinary anatomy

Background:

• The horse's neck plays a key role in balance during locomotion and stance.
• Increased interest in equine neck function is observed in equestrian sports, with debates on specific neck positions like hyperflexion.
• Recent research is focusing on the structures and functions of the equine neck.

Purpose of the Study:

• To provide an overview of new findings on equine neck structures and functions.
• To illustrate the interplay between the neck's anatomy and its role in locomotion and overall horse performance.
• To highlight the impact of neck posture on the central nervous system and training possibilities.

Main Methods:

• Review of current scientific literature on equine neck anatomy, biomechanics, and physiology.
• Analysis of the relationship between neck conformation, locomotion, and breed-specific work requirements.
• Examination of the effects of neck position on neurological structures and muscular function.

Main Results:

• The equine neck functions as a major balancing mechanism, utilizing visual, vestibular, and proprioceptive systems.
• Neck movement is integral to locomotion, with varying conformations suited for different tasks.
• Neck posture significantly impacts the trunk, limbs, and cervical spinal cord, influencing neural and muscular function.
• The neck stores elastic energy during locomotion, requiring muscle activity for stabilization, which declines with age.

Conclusions:

• The equine neck's structure and function are complex and integral to the horse's overall biomechanics.
• Rider influence on neck position offers a training avenue but also necessitates careful management to prevent injury.
• Age-related decline in muscle function highlights the importance of ongoing training for spinal health and injury prevention in horses.
