Study Notes
Cartilage
- Chondr/o is the root for cartilage.
- Smooth, rubbery blue-white connective tissue acts as a shock absorber and protects bone ends.
- Elastic tissue forms flexible parts of the skeleton, such as the outer ear and tip of the nose.
Articular Cartilage
- Covers surfaces of bones forming joints.
- Facilitates smooth joint movement and protects bones from friction.
Meniscus
- Curved fibrous cartilage located in joints, including the knee and temporomandibular joint.
Ligament
- Ligament/o refers to ligaments that connect bone to bone.
- Bands of fibrous connective tissue provide structural support.
Tendon
- Connects muscle to bone, facilitating movement and stability.
Joints
- Arthr/o is the root for joints, also known as articulations.
- Connect bones and work with muscles to enable a range of movements.
- Different joint types allow varying degrees of motion.
Synovial Membrane
- Synovi/o, synov/o are roots related to the synovial membrane.
- Lines synovial joints and secretes synovial fluid for lubrication.
- Encapsulates movable joints with a fibrous capsule.
Synovial Fluid
- Acts as a lubricant to enable smooth joint movement.
- Secreted by the synovial membrane surrounding movable joints.
Bursa
- Burs/o refers to a bursa, a fibrous sac containing synovial fluid.
- Cushions areas subject to friction, commonly found in joints like the shoulder, elbow, and knee.
Bone Marrow Types
- Red bone marrow is found in spongy bone, producing red and white blood cells and platelets.
- Yellow bone marrow, located in the medullary cavity, primarily stores fat.
Types of Cartilage
- Cartilage is a shock-absorbing connective tissue.
- Articular cartilage protects joints and facilitates movement.
- Meniscus consists of fibrous cartilage found in certain joints.
Types of Joints
- Sutures are immovable joints in the skull.
- Symphysis joints are formed by cartilage holding two bones together.
- Synovial joints are movable, allowing diverse motion (e.g., ball and socket, hinge joints).
Number of Bones
- The human skeleton consists of 206 bones.
Axial Skeleton
- Comprises 80 bones, primarily protecting major organs.
Appendicular Skeleton
- Contains 126 bones, facilitating body movement and protecting digestive and reproductive organs.
- Divided into upper and lower extremities.
Skull Bones
- Frontal bone forms the forehead.
- Parietal bones make up the top and sides of the skull.
- Occipital bone is at the back of the skull, allowing spinal cord passage.
- Temporal bone contributes to the side and base of the skull.
- Sphenoid bone forms the floor of the skull and part of the eye sockets.
- Ethmoid bone shapes the nose, eye orbits, and skull floor.
- External Auditory Meatus is the opening to the external ear located in the temporal bone.
- Zygomatic bones are commonly known as the cheekbones.
- Maxillary bone is the upper jawbone.
- Palatine bone forms the hard palate of the mouth.
- Lacrimal bones are associated with tear production and located in the inner eye.
