Summary
This study details the equine cervical intervertebral foramina (IVF) anatomy at C5/C6 and C6/C7. Findings enhance safety for equine surgical procedures like cervical foraminotomy.
Area of Science:
- Veterinary Anatomy
- Equine Surgery
- Neuroanatomy
Background:
- Equine cervical intervertebral foramina (IVF) are crucial for spinal nerve and vasculature passage.
- Existing literature lacks detailed equine cervical IVF anatomy for veterinary surgeons.
- Understanding IVF anatomy is vital for safe diagnostic and surgical procedures.
Purpose of the Study:
- To provide a comprehensive anatomical analysis of the C5/C6 and C6/C7 IVF in horses.
- To support the development of advanced clinical methodologies for cervical foraminotomy.
- To offer detailed anatomical descriptions relevant to equine veterinary surgeons.
Main Methods:
- Performed anatomical dissections on equine cadavers' necks.
- Evaluated external musculature for contextual orientation.
- Conducted intricate dissections and detailed descriptions of the C5/C6 and C6/C7 IVF.
- Utilized visual documentation and annotated diagrams for data analysis.
Main Results:
- Presented a sequential, detailed anatomical characterization of the C5/C6 and C6/C7 IVF.
- Highlighted morphological descriptions, structural orientation, and adjacent tissue planes.
- Delineated critical features for clinical practice, including proximity of neurovascular structures to bony landmarks.
Conclusions:
- The study offers novel anatomical interpretations of the equine cervical IVF region.
- Findings advocate for safer, evidence-based clinical practices in equine cervical surgery.
- Enhanced anatomical knowledge improves management of conditions requiring clinical and surgical interventions.

01:30General Structure of a Vertebra
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
01:17Structural Joints: Cartilaginous Joints
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

01:28Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
01:15Spinal Cord: Gross Anatomy
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
