Study Notes
- Ligaments connect bone to bone and provide joint stability
- Tendons connect muscle to bone and facilitate movement
Long and Short Bones
- Long bones are longer than they are wide, supporting weight and facilitating movement
- Examples of long bones include the femur, humerus, and tibia
- Short bones are cube-shaped, providing stability and support with little movement
- Examples of short bones include carpals (wrist bones) and tarsals (ankle bones)
Upper Limb Structures
Humerus
- The proximal end, or head, articulates with the scapula at the glenoid cavity
- The deltoid tuberosity of the shaft serves as the attachment site for the deltoid muscle
- The distal end includes the capitulum, which articulates with the radius, and the trochlea, which articulates with the ulna
Radius
- The radius is the lateral bone of the forearm
- The proximal end, or head, articulates with the capitulum of the humerus
- The distal end articulates with carpals and is involved in the wrist joint
Ulna
- The ulna is the medial bone of the forearm
- The olecranon process forms the elbow point at the proximal end
- The styloid process stabilizes the wrist joint at the distal end
Scapula Structure
- The acromion articulates with the clavicle
- The glenoid cavity articulates with the humerus
- The spine of the scapula is a bony ridge on the posterior surface
Carpal bones
- The carpal bones can be remembered using the mnemonic: "Some Lovers Try Positions That They Can’t Handle”
- Proximal row (lateral to medial): Scaphoid, Lunate, Triquetrum, Pisiform
- Distal row (lateral to medial): Trapezium, Trapezoid, Capitate, Hamate
- Carpals form the wrist joint
- Metacarpals are the palm bones, numbered I-V from thumb to pinky
Lower Limb Structures
Femur
- The femur is the longest and strongest bone in the body
- The head articulates with acetabulum of hip
- The distal end articulates with the tibia and patella
Tibia
- The tibia is the medial and larger bone of the lower leg
- The proximal end articulates with the femur
- The distal end forms the medial malleolus (ankle bone)
Fibula
- The fibula is the lateral, thinner bone of the lower leg
- It provides muscle attachment and stability
- The distal end forms the lateral malleolus (outer ankle bone)
Foot Structures
Talus
- The talus articulates with the tibia and fibula, forming the ankle joint
Calcaneus
- The calcaneus is the largest tarsal bone and forms the heel
Metatarsals vs Phalanges
- Metatarsals are the five bones that form the arch of the foot
- Phalanges are the toe bones
- There are proximal, middle, and distal phalanges in all toes except the big toe, which has only two
Axial vs Appendicular Skeleton
- The axial skeleton consists of the skull, vertebral column, and rib cage
- The appendicular skeleton consists of the limbs and girdles (pectoral and pelvic girdles)
Vertebrae
- There are 7 cervical vertebrae, which are small and have transverse foramina
- There are 12 thoracic vertebrae, which articulate with ribs, having a heart-shaped body
- There are 5 lumbar vertebrae, which are large, weight-bearing, with a thick body
Sacrum and Coccyx
- The sacrum consists of 5 fused vertebrae and articulates with the hip bones
- The coccyx consists of 3-5 fused vertebrae forming the tailbone
Skull Sutures
- The coronal suture is between the frontal and parietal bones
- The sagittal suture is between the two parietal bones
- The lambdoid suture is between the occipital and parietal bones
- The squamous suture is between the temporal and parietal bones
Skull Bones
- There are 8 cranial bones: Frontal, Parietal (2), Temporal (2), Occipital, Sphenoid, Ethmoid
- There are 14 facial bones: Nasal (2), Maxilla (2), Zygomatic (2), Mandible, Lacrimal (2), Palatine (2), Inferior Nasal Concha (2), Vomer
External Acoustic Meatus
- The external acoustic meatus is an opening in the temporal bone leading to the ear canal
Pelvic Bones
- The ilium is the largest, superior part of the pelvis
- The ischium is the inferior, posterior part of the pelvis, supporting weight when sitting
- The pubis is the anterior portion of the pelvis and forms the pubic symphysis
Carpal Bones
- The carpal bones are: Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate

Description
Ligaments connect bone to bone, providing joint stability, while tendons connect muscle to bone, facilitating movement. Long bones support weight and enable movement, while short bones offer stability with limited motion. Examples include the humerus and radius.
