Study Notes

Anatomy of the Spinal Column

The middle cranial fossa houses the temporal lobes of the brain, while the posterior cranial fossa houses the cerebellum.
The spinal column consists of 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 3-5 coccygeal vertebrae, each with specific functions and characteristics.
The spinal curves include primary curves (thoracic and sacral) that develop prenatally, and secondary curves (cervical and lumbar) that develop postnatally.
A typical vertebra consists of various parts, such as the vertebral body, vertebral arch, pedicles, laminae, spinous process, and transverse processes.
Structural variations in vertebrae reflect regional specializations in function, such as load-bearing capacity and spinal cord diameter.
The Atlas (C1) and Axis (C2) are specialized vertebrae with unique features, including superior articular facets and transverse foramina.
Intervertebral articulations involve the vertebral canal, intervertebral foramina, and zygapophyseal joints, allowing slight gliding movements between vertebrae.
Intervertebral discs consist of a fibrocartilaginous anulus fibrosus and a gelatinous core (nucleus pulposus), providing cushioning and flexibility.
The sacrum and coccyx are fused vertebrae with specific functions, including articulation with the lower limb and protection of pelvic viscera.
The anatomical position and directional nomenclature are essential for precise communication in anatomical descriptions, involving terms like cranial, caudal, dorsal, ventral, lateral, and medial.
The frontal or coronal plane is used to separate the body into anterior and posterior portions, aiding in anatomical descriptions and sectional nomenclature.
Understanding the precise language and directional terms is crucial for effective communication in the study and description of human anatomy.
