Labeling Bones Flashcards

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.
