MSA2 Test 1 Review
The name of the expanded portion at each end of a bone. It is the point of articulation.
What is the site of bone lengthening?
The shaft of the bone.
Two examples of flat bones
Two examples of short bones.
An example of a sesamoid bone
Two examples of amphiarthrotic joints
Three classifications of joints
In what type of joints are bones closely bound together with dense CT?
On what bone is the mastoid process found?
What are the largest sinuses and where are they found?
Floor of orbit to upper teeth
What bone forms the cheek bones?
What is the only movable bone of the facial skeleton?
What forms the vertebral column?
25 vertebrae and intervertebral discs (made of fibrocartilage)
What is the other name for C1?
What is the other name for C2?
What makes up the thoracic cage?
What makes up the pectoral girdle?
Fn of jts? (2)
bind bones together
allow movement and bone growth
Fn of articular cartilage (hyaline cartilage)?
Reduces friction during movement
Where is the synovial membrane?
The inner layer of the joint capsule
Main function of the inner layer of a joint capsule
Synovial membrane secretes synovial fluid = lubrication
What do ligaments connect?
bone to bone, which prevents excessive jt movement
Six types of synovial joints
Ball and socket (GH joint)
Ellipsoid (radiocarpal jt)
Hinge (humeroulnar jt)
Gliding (carpals or tarsals)
Pivot (1st & 2nd cervical vert)
Which type of synovial jt is this? Consists of oval-shaped end articulating with the elliptical basin of another bone. It permits flexion/extension and abduction/adduction.
Which type of synovial jt is this? It allows for only flexion/extension. Example: elbow
Which type of synovial jt is this? It's a modified ellipsoid jt composed of convex and concave articulating surfaces. Example- thumb
Which type of synovial jt is this? It's usually between two flat surfaces and allows for the least movement- only small shifting movements.
Which type of synovial jt is this? It's designed to allow one bone to rotate around the surface of another.
First and second cervical vertebrae are an example of which joint type?
Which type of synovial jt is this? Egg shaped head of bone articulates with cup shaped cavity of another.
Ball and socket
Why is the scapulothoracic "joint" not a real synovial joint?
The scapula is suspended on the rib cage by muscles
What movement is a bending that reduces the angle of a joint so that the parts come together within the sagittal plane?
What is movement of a limb away from the midline within the coronal plane?
What is the turning of the head/torso within the transverse plane?
From anatomical position, the turning of a limb toward the midline within the transverse plane.
Movement of the scapula in an arc lateral and superior in relation to the humerus in the coronal plane
Moving a part backward (scap or jaw)
Moving a part forward (scap or jaw)
Movement toward the midline within the transverse plane (shoulder joint)
Moving a body part so that its end follows a circular path
