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...

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure. Gray Matter and its Components Central to the gray matter is...

After spinal transection, adult zebrafish have functional recovery by six weeks post-injury. To take advantage of larval transparency and faster recovery, we present a method for transecting the larval spinal cord. After transection, we observe sensory recovery beginning at 2 days post-injury, and C-bend movement by 3 days post-injury.

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
FAQs
The coverings surrounding the spermatic cord are derived from layers of the abdominal wall encountered along its passage through the inguinal canal. Their continuity provides a useful anatomical landmark: clinicians can follow the cord’s route and recognize its relationship to the inguinal region during examination or operative access.
The pampiniform venous plexus contributes to temperature regulation around the testis. Because it is a named vascular component of the cord, changes involving this venous network are clinically relevant when assessing a varicocele. Understanding its position also helps distinguish venous structures from the testicular artery and other cord contents.
The cremasteric muscle gives the cord a movement-related component, while cremasteric vessels contribute to its vascular supply. Considering these structures separately from the ductus deferens, testicular artery, and pampiniform plexus clarifies how the cord supports both testicular positioning and circulation. This distinction is useful when interpreting anatomy in clinical settings.
These components perform different roles, including sperm transport, blood delivery, venous regulation, neural signaling, and lymphatic drainage. Mapping them individually prevents the cord from being treated as a single undifferentiated structure. That organization is particularly important when clinicians interpret disease or plan access to structures in the inguinal and testicular regions.
Anatomical knowledge gives clinicians a framework for relating examination findings to structures that may be involved. The same framework applies across inguinal hernias, varicoceles, torsion, trauma, and infections, where the relevant cord contents, coverings, or route through the inguinal canal may differ. It therefore supports focused clinical assessment.
Hernia repair, vasectomy, and orchiectomy each require accurate orientation within the spermatic cord region. The inguinal route and coverings matter during hernia repair, the ductus deferens is central to vasectomy, and orchiectomy requires awareness of the cord’s vascular, neural, and ductal contents. This anatomical knowledge supports precise procedural planning.
