Study Notes
Skull Bones
- Frontal Bone: The bone forming the forehead and part of the eye sockets.
- Maxilla Bone: The upper jawbone that houses the upper teeth and forms part of the orbit.
- Mandible Bone: The lower jawbone, the only movable bone of the skull.
- Sphenoid Bone: A butterfly-shaped bone at the base of the skull that articulates with several other cranial bones.
- Zygomatic Bone: Known as the cheekbone, it contributes to the orbit and sides of the face.
- Temporal Bone: Part of the lateral skull, contains structures important for hearing and balance.
- Occipital Bone: The back and base of the skull containing the foramen magnum.
- Parietal Bone: Paired bones forming the top and sides of the skull.
- Nasal Bone: Two small bones forming the bridge of the nose.
- Lacrimal Bone: Small bones forming part of the eye socket.
- Ethmoid Bone: A complex bone at the roof of the nasal cavity and part of the eye socket.
- Vomer: A single bone forming the lower part of the nasal septum.
Vertebrate and Spinal Anatomy
- Atlas: The first cervical vertebra, supports the head.
- Axis: The second cervical vertebra, allowing head rotation.
- Cervical Vertebrae: Seven vertebrae (C1-C7) in the neck region.
- Thoracic Vertebrae: Twelve vertebrae that articulate with the ribs, forming the thoracic spine.
- Lumbar Vertebrae: Five vertebrae in the lower back, designed for weight-bearing.
- Sacrum: Five fused vertebrae forming the posterior pelvis structure.
- Coccyx: The terminal part of the vertebral column, commonly known as the tailbone.
Bones of the Limbs
- Clavicle: The collarbone, connecting the arm to the body.
- Scapula: The shoulder blade, providing attachment for arm muscles.
- Humerus: The long bone of the upper arm from shoulder to elbow.
- Ulna: The inner and longer bone of the forearm, located on the pinky side.
- Radius: The outer and shorter bone of the forearm, located on the thumb side.
- Carpals: Eight wrist bones that articulate with the metacarpals.
- Metacarpals: Five bones that form the middle part of the hand.
- Phalanges: The bones of the fingers and toes.
Pelvic and Thigh Anatomy
- Coxal Bone: Hip bone consisting of ilium, ischium, and pubis.
- Femur: The longest bone in the body, known as the thigh bone.
- Tibia: The thicker bone in the lower leg located on the inner side.
- Fibula: The thinner bone in the lower leg located on the outer side.
- Patella: The kneecap; a sesamoid bone in front of the knee joint.
Foot and Ankle Structure
- Calcaneus: The heel bone.
- Talus: The ankle bone that articulates with leg bones.
- Tarsals: Seven bones that form the ankle.
- Metatarsals: Five bones of the foot that connect the ankle to the toes.
Ribcage Anatomy
- Sternum: The breastbone, articulating with clavicles and ribs.
- Manubrium: The upper section of the sternum.
- Xiphoid Process: The lower part of the sternum.
- True Ribs: The first seven pairs of ribs attaching directly to the sternum.
- False Ribs: Five pairs of ribs that attach indirectly to the sternum.
- Floating Ribs: The last two pairs of ribs that do not attach to the sternum.
Bone Structure and Growth
- Diaphysis: The main shaft of a long bone.
- Epiphysis: The extremities of a long bone.
- Medullary Cavity: Hollow center of long bones containing marrow.
- Epiphyseal Plate: Growth plate made of cartilage that allows for bone growth.
- Compact Bone: Dense outer layer providing strength to bones.
- Spongy Bone: Internal bone layer with a porous structure, found in the ends of long bones.
Specialized Cell Types
- Osteocyte: Mature bone cell embedded within the bone matrix.
- Osteoblast: Bone-forming cell responsible for new bone formation.
- Osteoclast: Bone-resorbing cell that breaks down bone tissue.
- Lacunae: Small cavities in bone housing osteocytes.
- Canaliculi: Tiny channels connecting lacunae, facilitating nutrient exchange.
