Planes of Movement
The sagittal plane divides the body into what portions?
Divides the body into left and right
What is the immovable joint separated by a thin layer of connective tissue?
Synarthrotic (FIBROUS JOINTS)
Give an example of a diarthrotic or synovial joint that is also a ball-and-socket joint:
Shoulder joint, hip joint.
The only saddle joint on the body is located where?
The thumb
Abduction and Adduction occur in this plane:
Frontal
The coronal plane divides the body into what portions?
Front and back or anterior/posterior portions
This type of joint movement is characterized as slightly moveable, and connected by hyaline cartilage:
Amphiarthrotic (CARTILAGINOUS JOINTS)
What are the six types of diarthrotic synovial joints in the body?
1. Ball and Socket
2. Ellipsoid/Condyle
3. Saddle
4. Pivot
5. Hinge
6. Gliding
Pivot joint. An example is the axis and atlas of the neck, and the forearm
Rotation occurs on this plane:
Transverse
Medial & Lateral, Flexion & Extension occur in this plane:
Sagittal
This type of joint is are freely moveable and most common in the appendicular skeleton:
Diarthrotic (SYNOVIAL JOINTS)
What axis is a ball-and-socket joint?
Multi-axis/Tri-axis
sagittal=flexion and extension
frontal=abduction and adduction
transverse=rotation
This joint allows for flexion and extension in the elbow and knee:
Hinge joint
The term "superior" refers to what structure?
Things that are superior are closer to the head
The transverse plane divides the body into:
Upper and lower, or superior/inferior
Give an example of a Synarthrotic or Fibrous joint:
Sutures of the skull, Ribs
An example of a ellipsoid or condyloid joint:
metacarpals, phalanges, metatarsals
Which joint allows for sliding or twisting without any circular movement?
Gliding joint as in the carpals and tarsals
If something is distal it means that it is what?
It is further away from the trunk or midline
What type of movement combines flexion, extension, abduction, and adduction?
Circumduction
Give an example of an amphiarthrotic or Cartilaginous joint:
What type of joint has both concave and convex regions, allowing for a wide range of movement?
Saddle joint
What type of joint is surrounded by a fibrous capsule, articular (hyaline) cartilage, joint cavity (synovial fluid), and reinforcing ligaments (bursae)?
Synovial Joints
A fluid-filled sac that cushion tendons where they cross the bones is what?
Bursae
