Study Notes
Skeletal System
-
Parietal Bone: Forms the sides and roof of the cranium, protecting the brain.
-
Occipital Bone: Located at the back of the skull, contains the foramen magnum for spinal cord passage.
-
Atlas (C1): The first cervical vertebra, supports the skull, allows nodding motion.
-
Axis (C2): The second cervical vertebra, has the odontoid process (dens) enabling rotation of the head.
-
Spinous Process of Thoracic Vertebra: Projects posteriorly; attachment site for muscles and ligaments.
-
Thoracic Vertebra: Twelve vertebrae connecting to ribs, accommodating thoracic cavity structures.
-
Floating Ribs: The last two pairs of ribs; not attached to the sternum, providing flexibility.
-
Humerus: The upper arm bone, articulates with the scapula and radius.
-
Ulna: The inner forearm bone, larger at the elbow end; forms the elbow joint.
-
Radius: The outer forearm bone, allows rotation of the wrist joint.
-
Carpal Bones: Eight wrist bones; facilitate a wide range of hand movements.
-
Ischial Tuberosity: The bony prominence of the ischium; supports weight when sitting.
-
Phalanges: The bones of the fingers and toes; each digit has three (two in the thumb/big toe).
-
Metatarsal Bones: Five long bones in the foot; provide structure and support for the toes.
-
Calcaneus: The heel bone; largest tarsal bone, essential for walking and standing.
-
Talus: The ankle bone, articulates with the tibia and fibula.
-
Fibula: The outer leg bone; provides stability to the ankle joint.
-
Femoral Condyle: The rounded ends of the femur that articulate with the tibia at the knee joint.
-
Femur: The thigh bone; the longest and strongest bone in the body, supports body weight.
-
Metacarpal Bones: Five bones in the hand connecting wrist to fingers, essential for hand function.
-
Pubis: Part of the pelvic bone, located at the front, contributes to the pelvis's structure.
-
Coccyx: Known as the tailbone, formed by four fused vertebrae, supports pelvic organs.
-
Sacrum: A triangular bone made of five fused vertebrae at the base of the spine, connects to hips.
-
Ilium: The largest part of the pelvis, forms the hip bone, and provides attachment for muscles.
-
Lumbar Vertebra: Five vertebrae in the lower back; support upper body weight and allow flexibility.
-
False Rib: Ribs 8-10; indirectly connected to the sternum via cartilage.
-
True Rib: Ribs 1-7; directly attached to the sternum, providing respiratory structure.
-
Scapula: The shoulder blade; connects the humerus with the clavicle and provides shoulder mobility.
-
Acromion: The lateral extension of the scapula; forms a bony prominence of the shoulder.
-
Spine of the Scapula: A ridge along the back of the scapula, muscle attachment site.
-
Clavicle: The collarbone; connects the arm to the trunk, aids in shoulder mobility.
-
Mandible: The lower jawbone; the only movable bone of the skull, crucial for chewing.
-
Tibia: The shinbone; larger and stronger than the fibula, supports body weight.
-
Zygomatic Bone: The cheekbone; contributes to the structure of the face and orbit.
