Study Notes

Musculoskeletal System

Musculoskeletal refers to the combined system of muscles and skeleton.

Orthopedics

A medical specialty focusing on preventing and correcting musculoskeletal system deformities and diseases, particularly of bones, muscles, joints, tendons, and ligaments.

Orthopedist

A healthcare professional specializing in bone disorders and associated structures across all age groups.

Bone Structure

Clavicle (collarbone): CF clavicul/o.
Cranium (skull): CF crani/o.
Costa (rib): CF cost/o.
Scapula (shoulder blade): CF scapul/o.
Sternum (breastbone): CF stern/o.
Spine: CF rachi/o, spin/o, forms the backbone.
Vertebrae: CF spondyl/o, vertebr/o, spinal bones of various types (cervical, thoracic, lumbar, sacrum, coccyx).

Major Limbs and Connective Bones

Humerus: CF humer/o, upper arm bone.
Radius (forearm): CF radi/o.
Ulna (forearm): CF uln/o.
Carpals: CF carp/o, wrist bones.
Metacarpals: CF metacarp/o, bones forming the hand.
Phalanges: CF phalang/o, bones of fingers and toes.
Femur: CF femor/o, thigh bone.
Patella: CF patell/o, kneecap.
Fibula and Tibia: CF fibul/o and tibi/o, lower leg bones.
Tarsals: CF tars/o, ankle bones.
Calcaneus: CF calcane/o, heel bone.
Metatarsals: CF metatars/o, foot bones.

Common Conditions and Terms

Rachiodynia / Rachiagia: pain in the spine.
Spondylitis: inflammation of a vertebra.
Intervertebral: located between two adjacent vertebrae.
Cerebrospinal fluid: clear fluid circulating in the brain and spinal cord.

Anatomy References

Lumb/o: lower back.
Lumbago: dull, aching pain in the lower back.

Rib and Joint Relations

True ribs: first 7 pairs directly attach to the sternum; false ribs: 5 pairs do not.
Intercostal: situated between the ribs.
Sternocostal: relation between sternum and ribs.

Joint Types

Synovial joints: have cavities for movement, contain synovial fluid (e.g., elbow, knee).
Bursae: fluid-filled sacs reducing friction in joints.

Movement Terms

Extension: action of straightening a limb.
Flexion: action of bending a limb.

Tissue Types

Osteoid: resembling bone.
Calcification: process of tissue hardening due to calcium deposits.
Osteomalacia: bone softening due to calcium loss.
Osteomyelitis: bone inflammation often involving marrow.
Chondral: pertaining to cartilage and its structures.

Terminology Components

CF (Combining Form): indicates anatomical or pathological terms' roots.
Prefixes like "de-" (down) and "meta-" (change or next) can alter meanings.
Suffix "-sarcoma": indicating a malignant tumor in connective tissue.
