Joints Flashcards
Joints
2 bones meeting, articulating in an area
What can limit movement of a joint?
surface of bone, obstruction, ligaments
Fibrous joints
a type of joint that connects bones with dense, fibrous connective tissue. They are characterized by their limited or no mobility.
Permanent articulation to prevent damage, combined by immovable sutures, like the skull that surrounds the brain
Cartilaginous joints
a type of joint that connects bones using cartilage. They are found in various parts of the body and provide stability and limited movement.
Slightly moveable, intervertebral disks allow slight movement between vertebrae
Sinovial joints
Freely moving; freely movable joints that enable smooth and flexible movement between bones.
Types: (do not have to list)
Plane: Gliding or sliding movements (e.g., wrist, ankle)
Hinge: Flexion and extension (e.g., elbow, knee)
Pivot: Rotation around a single axis (e.g., neck)
Condyloid (ellipsoidal): Movement in two planes (e.g., wrist, thumb)
Saddle: Movement in two planes plus a twisting motion (e.g., thumb at the base of the finger)
Ball and Socket: Movement in all three planes (e.g., shoulder, hip)
Ball and socket joints
Movement in all three planes (e.g., shoulder, hip) greatest mobility in all planes
Hinge joint
Flexion and extension (e.g., elbow, knee); moves forward and back like a door hinge
Pivot joint
Rotation around a single axis (e.g., neck); the joint between the radius and ulna bones in your forearm, enabling rotation of your hand.
condiloid joints
joints in hands and fingers
Gliding joints
Plane joints
Where bones meet are flat and bones glide over other where they join; writ and ankles
Saddle joints
Thumb, wrist, and hips; one bone is shaped like a saddle and other bone rets on it like a rider on a horse; some people have more mobility or flexibility at these joints
Connective tissue that binds parts of bones
Ligaments
Tendons
Fascia
Ligaments
Connects bone to bone; slightly flexible and strong structure; they do not stretch
Tendons
absorb tension and connect muscle to bone
Fascia
Connects entire body together; muscle to muscle tissue to tissue; like a stocking or web that connects everything to our brain; psychosomatic issues may be trapped in the fascia from trauma
PRICE for first-aid treatment stands for…
Protection, Rest, Ice, Compression, and Elevation; it’s a common acronym used to describe the first-aid treatment for injuries like sprains or strains, aiming to reduce pain and swelling by protecting the affected area, resting it, applying ice, compressing it, and elevating it above the heart level.
