Joints (Exam 2) Flashcards
The two terms describe a point where two bones meet.
Articulation and joint
The glenohumeral joint is where the scapula meets the humerus and what other structure?
Glenoid cavity
A bony, immovable joint is called a(n)
Synostosis
What is another term for a fibrous joint?
Synarthrosis
Which class of joints includes sutures and gomphosis?
Fibrous
Where are sutures found?
Only in the skull
The anatomical name of a joint is determined by the manner in which the bone ends are connected at the joint.
False
Synarthrotic fibrous joints between the bones of the skull are called
sutures
Which is produced by embryonic bones fusing seamlessly into one adult bone?
Synostosis
What holds the bones together in a fibrous joint?
Collagen fibers
What are the three types of fibrous joints?
Sutures,syndesmoses, and gomphoses
The pubic symphysis is an example of which type of joint?
Cartilaginous
Synchondroses and symphyses are types of what kind of joint?
Cartilaginous
joint type is most likely to develop dysfunction due to its complexity
Synovial
In a symphysis, bones are held together by which of the following?
fibrocartilage
the types of cartilaginous joints.
Synchondroses and Symphyses
What is the hyaline cartilage found at the end of the bones within a synovial joint called?
Articular cartilage
Tendons can serve which of the following functions?
Attach muscle to bone and Stabilize a joint
A strip of tough collagenous tissue attaching a bone to another bone is called a
ligament
A structure that is an elongated structure that is utilized to generate a mechanical advantage around a fulcrum is called a(n)
lever
Intervertebral discs comprised of fibrocartilage are found within what type of joints?
Symphyses
In a musculoskeletal lever system, what force does the muscle contraction provide?
Effort
If a lever’s mechanical advantage is less than 1.0, which of the following is true?
The lever produces more speed or distance (but less force) than the force exerted on it.
Extending a joint beyond the zero position is always an abnormal movement.
False
What is formed by an elongated, rigid object rotating around a fulcrum?
Lever
Movement of the foot so that the toes are elevated off of the ground is called
dorsiflexion
Within the skeletal anatomy, what supplies the effort?
Muscle contraction
Which two bones articulate to form the jaw joint?
Mandible and temporal
A joint that is extended beyond zero position is said to be what?
hyperextended
What factors allow the shoulder to have a wide range of motion?
Loose joint capsule and shallow joint cavity
What is the movement of toes downward, as when jumping or stepping on a gas pedal, called?
Plantar flexion
What are the two articulations of the elbow joint?
Humeroulnar and Humeroradial
What is another name for the hip joint?
Coxal joint
The ankle joint is also referred to as the
talocrural joint
What is the anatomical name for the shoulder joint?
Glenohumeral joint
Which joint is the most complex diarthrosis in the body?
knee
