Human Skull Anatomy Quiz

Frontal Bone: Forms the forehead and the upper eye sockets.
Parietal Bone (2): Located on the sides and top of the skull; contributes to the cranial cavity.
Temporal Bone (2): Situated below the parietal bones; houses structures of the inner and middle ear.
Occipital Bone: Forms the back and base of the skull; contains the foramen magnum.
Sphenoid Bone: Unique bone that connects the cranial bones; located at the base of the skull.
Ethmoid Bone: Forms part of the nasal cavity and the orbits; contains the cribriform plate.

Mandible: The lower jawbone; the largest and strongest facial bone.
Maxilla (2): Forms the upper jaw and part of the orbits; supports upper teeth.
Palatine Bone (2): Forms the back part of the hard palate and part of the nasal cavity.
Zygomatic Bone (2): Known as the cheekbones; forms part of the orbit.
Nasal Bone (2): Small bones forming the bridge of the nose.
Lacrimal Bone (2): Small bones forming part of the eye socket; also houses the tear ducts.
Vomer: Forms the lower part of the nasal septum.
Hyoid Bone: Supports the tongue and is not directly connected to other bones.

Cervical Vertebrae (7): The first section of the spine; includes atlas and axis.
Atlas: First cervical vertebra; supports the skull.
Axis: Second cervical vertebra; allows head rotation.
Thoracic Vertebrae (12): The middle section of the spine; articulates with the ribs.
Lumbar Vertebrae (5): Lower back vertebrae; larger and support more weight.
Sacrum: Composed of five fused vertebrae; connects to the pelvis.
Coccyx: Consists of four fused vertebrae; commonly known as the tailbone.

True Ribs (1-7): Directly attached to the sternum via cartilage.
False Ribs (8-10): Indirectly attached to the sternum.
Floating Ribs (11-12): Not attached to the sternum; provide minimal support.

Humerus (2): The long bone of the upper arm; connects to the shoulder and elbow.
Ulna (2): The inner bone of the forearm; longer than the radius.
Radius (2): The outer bone of the forearm; allows wrist rotation.
Carpals (16): Eight wrist bones, including pisiform, triquetrum, lunate, scaphoid, hamate, capitate, trapezoid, trapezium.
Metacarpals (10): Five bones forming the hand.
Phalanges of the Hand: Three types - proximal (10), middle (8), and distal (10).

Ilium (2): The large, flaring section of the hip bone.
Ischium (2): The lower part of the hip bone; forms the seat.
Pubis (2): The front section of the hip bone; fuses with the ischium and ilium.
Femur (2): The thigh bone; longest bone in the body.
Patella (2): The kneecap; protects the knee joint.
Tibia (2): The larger, weight-bearing bone of the lower leg.
Fibula (2): The smaller bone of the lower leg; stabilizes the ankle.

Tarsals (14): Seven ankle bones, including calcaneus, talus, navicular, cuboid, and three cuneiforms (lateral, intermediate, medial).
Metatarsals (10): Five bones of the foot.
Phalanges of the Foot: Three types - proximal (10), middle (8), and distal (10).

Supraorbital Foramen: Canal above the eye socket for blood vessels and nerves.
Zygomatic Process: Projection forming the cheekbone.
Mastoid Process: Projection behind the ear; serves as a muscle attachment site.
Styloid Process: Prominent projection for muscle attachment on temporal bone.
Foramen Magnum: Large opening at the base of the skull for the spinal cord.
Occipital Condyles: Rounded processes allowing skull articulation with the spine.
Sella Turcica: Depression housing the pituitary gland.
Crista Galli: Projection from the ethmoid bone; attaches to the dura mater.

Human skeleton consists of 206 bones, each with specific names and functions.
Bones vary between individuals but share common structures and anatomical relationships.
