Study Notes

Anatomy and Physiology of the Spinal Column

The middle cranial fossa contains the temporal lobes of the brain, while the posterior cranial fossa houses the cerebellum.
The spinal column consists of cervical, thoracic, lumbar, sacral, and coccygeal regions, each with a specific number of vertebrae.
Spinal curves include primary curves (thoracic and sacral) that develop prenatally and secondary curves (cervical and lumbar) that develop postnatally.
The anatomy of a typical vertebra includes various components such as the vertebral body, vertebral arch, pedicles, laminae, spinous and transverse processes, and articular processes.
Regional variations in vertebrae reflect specialized functions and movements, with structural differences such as the size of the vertebral body, diameter of the vertebral canal, and processes.
The Atlas (C1) and Axis (C2) are specialized vertebrae that articulate with the occipital condyles and accommodate the vertebral arteries.
Intervertebral articulations involve the vertebral canal, intervertebral foramina, and zygapophyseal joints, allowing slight gliding movements.
The sacrum, originating from five sacral vertebrae, articulates with the lower limb, provides muscle attachment, and protects pelvic viscera.
The coccyx, originating from 3-5 coccygeal vertebrae, begins fusing in early adulthood and provides attachment for the perineum.
Nomenclature and directional terms are important in anatomical language, including positions such as superior, posterior, anterior, ventral, caudal, lateral, medial, proximal, and distal.
The anatomical position and directional nomenclature help in describing the relative positions of anatomical structures and are essential in accurate communication within the field of anatomy.
Sectional nomenclature includes terms such as frontal or coronal plane, which separates the body into anterior and posterior portions.

Anatomy of Synovial Joints and the Skull

Synovial membrane covers nonarticular surfaces and secretes synovial fluid, acting as a lubricant and shock absorber
Accessory structures of synovial joints include articular discs, fat pads, tendons, and bursae
Intrinsic and extrinsic ligaments contribute to the stability and mobility of synovial joints
Functional classification of synovial joints includes linear motion, angular motion, circumduction, and rotation
Structural classification of synovial joints encompasses gliding, hinge, pivot, ellipsoidal, saddle, and ball-and-socket joints
The axial skeleton consists of the skull, vertebral column, sacrum, coccyx, and thoracic cage
The appendicular skeleton comprises the pectoral and pelvic girdles, as well as the upper and lower limbs
The skull includes the cranium, which houses the brain, and facial bones, which surround the entrances to the digestive and respiratory tracts
The anterior view of the skull shows the frontal bone, maxillae, nasal bones, zygomatic bones, and mandible
The superior view of the skull features the frontal and parietal bones, as well as the coronal and sagittal sutures
The posterior view of the skull displays the parietal and occipital bones, along with the external occipital protuberance
The lateral view of the skull highlights the temporal, frontal, nasal, zygomatic, and mandible bones, as well as the sphenoid bone
