1
New cards

Articulation (joint)

A point where two bones meet that allows movement; higher motion can lead to greater instability (ROM vs stability)

2
New cards

Range of motion (ROM)

The extent of movement allowed at a joint; as ROM increases, stability generally decreases

3
New cards

Hinge joint

A joint that allows movement in one plane (e.g., elbow and knee)

4
New cards

Gliding joint

Joints with small, flat bone surfaces that glide past one another to produce limited movement (carpals/tarsals)

5
New cards

Ball-and-socket joint (bone socket joint)

A joint with a ball-like end fitting into a cup, allowing wide range of motion but with less inherent stability (e.g., shoulder, hip)

6
New cards

Temporomandibular joint (TMJ)

The jaw joint; primarily a hinge to open and close the mouth

7
New cards

Compound joints

Joints that do not move in just one way; exhibit multiple directions of motion (e.g., spine with coupled motion)

8
New cards

Cervical spine

Neck region of the spine; capable of flexion/extension, lateral flexion, and rotation

9
New cards

Lateral flexion

Side bending of the spine; in the cervical spine, vertebrae may rotate toward the same side in the same direction

10
New cards

Lumbar spine rotation

Rotation of the lower spine, described as rotating in the opposite direction relative to lateral flexion

11
New cards

Saddle joint

Joint between the first metacarpal and proximal phalanx of the thumb; allows thumb opposition; commonly first carpometacarpal joint; prone to degeneration with age

12
New cards

Fibrous joints

Immovable joints connected by dense connective tissue (e.g., skull sutures, tooth sockets)

13
New cards

Cartilaginous joints

Bones joined by cartilage; slightly movable (e.g., pelvis, rib cage, intervertebral disks; poor blood supply)

14
New cards

Synovial joints

Joints where bones come together within a capsule containing synovial fluid and usually hyaline cartilage for smooth movement

15
New cards

Hyaline cartilage

Smooth, glassy cartilage covering joint surfaces to reduce friction during movement

16
New cards

Synovial fluid

Lubricant within the joint capsule that allows surfaces to move smoothly without grinding

17
New cards

Meniscus

Dense connective tissue discs that act as spacers/shock absorbers in joints (e.g., knee)

18
New cards

Axial skeleton

The central skeleton: skull, vertebral column, rib cage, sternum, hyoid; supports and protects the body’s core

19
New cards

Hyoid

Bone located under the mandible; anchor for the root of the tongue

20
New cards

Periosteum

Outer, tough fibrous layer of bone that contains blood vessels and nerves

21
New cards

Compact bone

Hard, dense outer layer of bone providing strength and protection

22
New cards

Spongy bone (cancellous bone)

Porous, honeycomb interior; lighter and more flexible yet strong

23
New cards

Bone marrow

Soft tissue inside bone cavities; yellow marrow stores fat; red marrow produces blood cells

24
New cards

Diaphysis

The long central shaft of a long bone, mainly compact bone

25
New cards

Epiphysis

The wider ends of a long bone, mainly consisting of spongy bone

26
New cards

Metaphysis

Transitional region between the diaphysis and epiphysis in a long bone

27
New cards

Medullary cavity

Central cavity of bone where yellow and red marrow reside

28
New cards

Endosteum

Tissue lining the inner surfaces of bone

29
New cards

Osteocytes

Mature bone cells within bone tissue

30
New cards

Osteoblasts

Bone-forming cells that build new bone

31
New cards

Osteoclasts

Bone-resorbing cells that break down bone during resorption

32
New cards

Fracture

A break or crack in a bone
