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.

Frontal Bone Articulation

The frontal bone articulates with the following bones:
- Parietal
- Sphenoid
- Ethmoid
- Zygomatic
- Maxilla
The temporal bone does not articulate with the frontal bone.

Hip Joint

The iliofemoral ligament significantly prevents overextension (hyperextension) at the hip joint.

Infratemporal Fossa

The inferior orbital fissure allows communication between the infratemporal fossa and the orbital cavity.

Anatomical Terms

Posterior: towards the back
Ipsilateral: on the same side of the body
Supine: lying face up

Facial Skeleton

Each of the following bones contributes to the facial skeleton:
- Maxilla
- Mandible
- Nasal
- Lacrimal
- Zygomatic
- Palatine
- Vomer
- Inferior nasal conchae
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.
