    Study Notes

    Joint Function

    • Friction reduction and shock absorption are functions of articular cartilage
    • Synovial fluid also contributes to shock absorption and lubrication, aiding in smooth joint movement.

    Humerus

    • The capitulum and trochlea are found at the distal end of the humerus.
    • The olecranon fossa and coronoid fossa are also found at the distal end.

    Paranasal Sinuses

    • Sphenoid, ethmoid, frontal, and maxillary sinuses are considered paranasal sinuses.
    • The mastoid air cells are not part of the paranasal sinuses system.

    The Carotid Canal

    • The carotid artery passes through the carotid canal located in the temporal bone.

    Middle Cranial Fossa

    • The foramen ovale, foramen spinosum, and foramen rotundum are all openings associated with the middle cranial fossa.
    • The foramen magnum and hypoglossal canal are not associated with the middle cranial fossa.

    Paranasal Sinuses in Bones

    • There are no paranasal sinuses in the following bones:
      • Parietal
      • Occipital
      • Temporal

    Ribs

    • A typical rib has a head, neck, tubercle, body, and angle.
    • Costal cartilage does not form part of a typical rib but connects the rib to the sternum.

    Orbit

    • The frontal, sphenoid, zygomatic, ethmoid, and maxilla bones form the orbit.
    • The lacrimal bone is included in the orbit.
    • The mandible does not form any part of the orbit.

      • Parietal
      • Sphenoid
      • Ethmoid
      • Zygomatic
      • Maxilla
    • The temporal bone does not articulate with the frontal bone.

    • The frontal bone is part of the cranial skeleton, not the facial skeleton.

    Pterygopalatine Fossa

    • The pterygopalatine fossa communicates with the oral cavity through the pterygomaxillary fissure.

    Ribs and Articulation

    • Seven pairs of ribs directly articulate with the sternum.

    Axial Skeleton

    • The clavicle and scapula are part of the appendicular skeleton.
    • The skull, vertebral column, and rib cage form the axial skeleton.

    Paranasal Sinus Drainage

    • The frontal sinus drains into the middle meatus via the frontoethmoidal duct.
    • The sphenoid sinus drains into the sphenoethmoidal recess.
    • The other paranasal sinuses (ethmoid and maxillary) all drain into the middle meatus.

    Pivot Joint Movement

    • Rotation is the type of movement normally seen at pivot joints.

    Gomphosis

    • The periodontal ligament is the connective tissue joining structure in a gomphosis.

    Saddle Joint

    • Saddle joints allow for biaxial movements, meaning movement in two planes. It's shaped like a saddle, allowing for flexion/extension, abduction/adduction, and circumduction.

    Superior Orbital Fissure

    • The superior orbital fissure is located between the greater wing of the sphenoid bone and the body of the sphenoid bone.

    Medial Ankle Prominence

    • The prominence felt on the medial surface of the ankle is part of the medial malleolus, which is a projection of the tibia.

    Coronoid Process

    • The coronoid process belongs to the mandible.

    Forearm Position

    • When your palms are lying flat on the table, your forearms are in pronation.

    Anatomical Plane

    • The midsagittal plane divides the body into equal right and left halves.

    Ethmoid Bone Articulation

    • The ethmoid bone in the nasal septum articulates with the vomer.

    Osteons

    • Osteons are the characteristic structural units of compact bone.

    Sutures

    • The metopic suture usually fuses in early childhood and generally does not persist in adulthood.

    Nasal Cavity Roof

    • The cribriform plate of the ethmoid bone forms the roof of the nasal cavity.

    Temporal Bone Parts

    • The squamous part of the temporal bone contains the external acoustic meatus.

    Long Bone Ends

    • The distal and proximal ends of a long bone are called the epiphyses.

    Superior Limb Attachment

    • The sternoclavicular joint serves as the only bony attachment of the superior limb to the axial skeleton.

    Bones with Two of Each

    • There are normally two of each of the following bones EXCEPT the vomer.

    Sphenoid Foramina

    • The foramina found in the sphenoid bone include:
      • Foramen ovale
      • Foramen lacerum
      • Foramen rotundum
      • Optic canal
      • Superior orbital fissure
    • The foramen magnum is located in the occipital bone.

    Epiphyseal Plate

    • The epiphyseal plate is responsible for longitudinal bone growth.

    Vertebra Structure

    • A typical vertebra consists of a body, vertebral arch, spinous process, transverse process, and lamina.
    • Costal facets are present only in thoracic vertebrae.

    Elevation and Depression

    • You can elevate and depress your scapula, mandible, and hyoid bone.

    Pterygopalatine Fossa Opening

    • The pterygopalatine fossa opens into the nasal cavity through the sphenopalatine foramen.

    Middle Cranial Fossa Openings

    • The foramen ovale, foramen spinosum, and foramen rotundum open into the middle cranial fossa.
    • The superior orbital fissure does not open into the middle cranial fossa.

    Movement Between Articulating Bones

    • Movement that increases the angle between articulating bones is called extension.

    Lamina Cribrosa

    • Lamina cribrosa is located in the ethmoid bone.

    Hemopoiesis

    • Hemopoiesis or blood cell formation occurs in the red bone marrow.

    Pterygopalatine Fossa Communication

    • The pterygopalatine fossa communicates with the middle cranial fossa through the pterygoid canal.

    Synchondrosis Example

    • The sternocostal joint is an example of a synchondrosis (cartilaginous joint).

    Glabella

    • The glabella is found on the frontal bone.

    Anatomical Position

    • A person in anatomical position exhibits all of the following except palms facing the body.

    First Cervical Vertebra

    • The atlas (C1), the first cervical vertebra, has no body and instead has two lateral masses connected by anterior and posterior arches.

    Long Bone Shaft

    • The diaphysis is the shaft of a long bone.

    Hinge Joints

    • The hinge joint allows for uniaxial movement, meaning movement in one plane. It resembles a door hinge, primarily allowing flexion and extension.

    Ellipsoid Joints

    • The ellipsoid joint is biaxial, allowing for flexion/extension, abduction/adduction, and circumduction. It resembles the shape of an egg, allowing for movement in two planes.
