Study Notes
Bone Structure Overview
- The human skeleton comprises various bones, categorized into cranial, facial, and appendicular regions.
- Noteworthy bones include the Frontal, Maxilla, Mandible, Sphenoid, and Zygomatic, which play significant roles in the structure and function of the skull and facial features.
Cranial Bones
- Frontal Bone: Forms the forehead; protects the frontal lobe of the brain.
- Parietal Bone: Paired bones forming the roof and sides of the skull.
- Temporal Bone: Sides of the skull, houses the ear structures.
- Occipital Bone: Back of the skull, contains the foramen magnum for spinal cord passage.
- Sphenoid Bone: Butterfly-shaped bone, contributes to the skull's base and eye socket structure.
- Ethmoid Bone: Supports the nasal cavity; contains sinuses and contributes to eye socket formation.
Facial Bones
- Maxilla: Upper jawbone; supports the teeth, contributes to the formation of the eye sockets.
- Mandible: Lower jawbone; the only movable bone of the skull.
- Zygomatic Bone: Cheekbone; adds structure and shape to the face.
- Nasal Bone: Forms the bridge of the nose.
- Lacrimal Bone: Smallest bones of the face; part of the eye socket.
- Vomer: Forms part of the nasal septum.
Appendicular Skeleton
- Clavicle: Collarbone; connects the arm to the body and stabilizes the shoulder.
- Scapula: Shoulder blade; supports arm movement.
- Humerus: Arm bone extending from shoulder to elbow.
- Ulna: Inner bone of the forearm, longer bone, found on the pinky side.
- Radius: Outer bone of the forearm, shorter bone, found on the thumb side.
- Carpals: Eight wrist bones facilitating hand movement.
- Metacarpals: Five bones forming the middle part of the hand.
- Phalanges: Finger and toe bones.
Pelvic and Lower Limb Bones
- Coxal Bone: Composed of ilium, ischium, and pubis; forms the hip structure.
- Femur: The longest bone in the body, also known as the thigh bone.
- Tibia: The larger, inner bone of the lower leg; supports weight and movement.
- Fibula: Smaller, outer bone of the lower leg; stabilizes the ankle.
- Patella: Also known as the kneecap; protects the knee joint.
Ankle and Foot Bones
- Calcaneus: The heel bone, providing structure and support to the foot.
- Talus: Bone that articulates with the leg bones to form the ankle joint.
- Tarsals: Seven bones of the ankle.
- Metatarsals: Five long bones in the foot, support weight and enable movement.
- Phalanges: Bones of the toes.
Thoracic Skeleton
- Sternum: Flat bone connecting with clavicles and ribs; protects heart and lungs.
- Manubrium: Upper section of the sternum.
- Body of Sternum: Middle portion providing attachment for ribs.
- Xiphoid Process: Lower tip of the sternum.
Rib Cage
- True Ribs: First seven pairs of ribs directly attached to the sternum.
- False Ribs: Last five pairs; indirectly connected to the sternum or not at all.
- Floating Ribs: Last two pairs; do not connect to the sternum.
Vertebral Column
- Cervical Vertebrae: Seven vertebrae (C1-C7) supporting the neck; includes atlas (C1) and axis (C2).
- Thoracic Vertebrae: Twelve vertebrae supporting the chest and attaching ribs.
- Lumbar Vertebrae: Five vertebrae in the lower back, supporting weight and movement.
- Sacrum: A triangular bone formed by five fused vertebrae, part of the pelvis.
