Learning Module 3:
The Skeletal System
The Skeletal System
Study the Learning Module and take the Quiz.
Learning Objectives:
- Name the major bones of the human body.
- Locate the major bones of the human body.
Head - The Skull
- Cranium - Frontal, Parietal, Occipital, Temporal, Sphenoid
- Face - Maxillary, Zygomatic, Mandible
Neck – Cervical Vertebrae (C1-C7)
Trunk
Chest – Sternum, Clavicle, Scapula, and Ribs (12 pairs)
Trunk
- Upper Back - Thoracic Vertebrae (T1-T12)
- Lower Back - Lumbar Vertebrae (L1-L5)
Chest – Sternum, Clavicle, Scapula, and Ribs (12 pairs)
- Costal cartilage attaches the anterior part of ribs 1-11 to the sternum
- Rib 12 is a “floating” rib (unattached anteriorly)
- The posterior part of each of the 12 ribs attach to a Thoracic Vertebra by an arthrodial joint (not synovial). These joints articulate upward with each inspiration and downward with each expiration.
- Laterally, the Clavicle (anterior) and Scapula (posterior) form the Shoulder Girdle for the attachment of the arm.
Pelvis - The Pelvic Girdle
- Anterior - Pubis
- Lateral and Superior - Ilium (hip)
- Inferior - Ischium
Bones of the Upper & Lower Limbs
Upper Limb
- Arm - Humerus
- Forearm - Ulna (medial) & Radius (lateral)
- Wrist - Carpals (8)
- Palm - Metacarpals (5)
- Fingers - Phalanges - proximal, middle, and distal (14)
Lower Limb
- Thigh - Femur
- Knee - Patella
- Leg - Tibia (thick, medial) & Fibula (thin, lateral)
- Ankle - Tarsals (7)
- Heel - Calcaneus (the largest tarsal bone)
- Sole - Metatarsals (5)
- Toes - Phalanges - proximal, middle, and distal (14)
