    Study Notes

    Anatomy of Synovial Joints and Skull

    • Synovial membrane secretes synovial fluid, which acts as a lubricant, shock absorber, and medium for solute transfer between blood and cartilages
    • Accessory structures of synovial joints include articular discs, fat pads, tendons, and bursae, which facilitate relative movement between structures
    • Intrinsic ligaments are thickenings of the joint capsule, while extrinsic ligaments can be intracapsular or extracapsular
    • Stability is inversely proportional to mobility, and it is influenced by the shape of articulating surfaces, capsule, ligaments, tone of surrounding muscles, and other tissues around the joint
    • Functional classification of synovial joints includes various types of movement such as linear motion, angular motion, circumduction, and rotation
    • Structural classification of synovial joints includes gliding, hinge, pivot, ellipsoidal, saddle, and ball-and-socket joints
    • The axial skeleton consists of the skull, vertebral column, sacrum, coccyx, and thoracic cage, while the appendicular skeleton consists of the pectoral girdles, upper limbs, pelvic girdles, and lower limbs
    • The skull includes the cranium, which houses the brain and provides muscular attachment, and facial bones that surround entrances to digestive and respiratory tracts
    • The skull can be viewed from different perspectives, including anterior, superior, posterior, and lateral views, each showing specific bone structures and features
    • The temporal bone contains various parts such as the zygomatic process, squamous part, squamous suture, pterion, external acoustic meatus, mastoid process, temporomandibular joint (TMJ), and styloid process
    • Cavities within the skull include the cranial cavity, orbits, nasal cavities, paranasal air sinuses (frontal, ethmoidal, maxillary, and sphenoid), and the oral cavity
    • The base of the cranium consists of the frontal bone, parietal bones, occipital bone, temporal bones (squamous and petrous parts), and foramen magnum; it also includes the sphenoid bone with its greater wing, lesser wing, and hypophyseal fossa or sella turcica, and the ethmoid bone with its cribriform plate, crista galli, and lateral masses containing the ethmoid air cells

    Anatomy of Synovial Joints and Skull

    • The skull can be viewed from different perspectives, including anterior, superior, posterior, and lateral views, each showing specific bone structures and features
    • The temporal bone contains various parts such as the zygomatic process, squamous part, squamous suture, pterion, external acoustic meatus, mastoid process, temporomandibular joint (TMJ), and styloid process
    • Cavities within the skull include the cranial cavity, orbits, nasal cavities, paranasal air sinuses (frontal, ethmoidal, maxillary, and sphenoid), and the oral cavity
    • The base of the cranium consists of the frontal bone, parietal bones, occipital bone, temporal bones (squamous and petrous parts), and foramen magnum; it also includes the sphenoid bone with its greater wing, lesser wing, and hypophyseal fossa or sella turcica, and the ethmoid bone with its cribriform plate, crista galli, and lateral masses containing the ethmoid air cells

    Anatomy of the Spinal Column and Cranial Fossae

    • The middle cranial fossa contains the temporal lobes of the brain.
    • The posterior cranial fossa houses the cerebellum and is comprised of various vertebral regions, including cervical, thoracic, lumbar, sacral, and coccygeal.
    • There are primary and secondary spinal curves, with the cervical curve developing with the ability to hold the head up and the lumbar curve critical in maintaining balance.
    • A typical vertebra consists of 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, with structural differences reflecting regional differences in function and movement.
    • The Atlas (C1) and the Axis (C2) are specialized vertebrae, with the Atlas having superior articular facets that articulate with the occipital condyles, while the Axis has a dens originally from the body of the Atlas.
    • Intervertebral articulations include the vertebral canal housing the spinal cord, intervertebral foramina accommodating spinal nerves, and zygapophyseal joints allowing slight gliding movements.
    • Intervertebral discs consist of a fibrocartilagenous anulus fibrosus and a gelatinous core, the nucleus pulposus, surrounded by various intervertebral ligaments.
    • The sacrum articulates with the lower limb, provides muscle attachment, and protects pelvic viscera, while the coccyx originates as 3-5 coccygeal vertebrae and begins fusing in early adulthood.
    • The sacrum and coccyx have various features, including transverse ridges, sacral foramina, the sacral promontory, and an auricular surface that articulates with the pelvic girdle.
    • Precise language is important in anatomy, with specific directional terms used to describe anatomical positions and nomenclature.
    • Directional terms include cranial/cephalic, caudal, proximal, distal, lateral, medial, superficial, and deep, used to describe the relative positions of anatomical structures.
