CBIO 2200: Exam 4
1. The atlantoaxial joint is between
|
Atlas and axis
|
1. Joints can be classified according to the
|
Structure or function of the joint
|
1. A place where two or more bones come together is a(n)
|
Joint and an articulation
|
1. The symphysis pubis is between the
|
Two pubic bones
|
1. A joint that has no joint cavity and exhibits little or no movement would be
|
Fibrous joint
|
1. The joint between the teeth and mandibular alveolus is an example of a
|
Gomphosis
|
1. Cartilaginous joints
|
Unite two bones by means of fibrocartilage or hyaline cartilage
|
1. In a syndesmosis
|
The bones are held together by collagenous fibers called interosseous
|
1. The epiphyseal plate of a growing is actually a temporary joint called a
|
Synchondrosis
|
1. A synchondrosis contains _______ cartilage
|
Hyaline
|
1. An example of a symphysis is the
|
Joint between vertebral bodies
|
1. Articular cartilage
|
Covers the ends of bones in synovial joints
|
1. The function of a bursa is to
|
Provide a fluid-filled cushion that reduces friction
|
1. Synovial joints are different from both fibrous and cartilaginous joints because synovial
|
Are enclosed by a joint capsule
|
1. Synovial fluid
|
Decrease friction between bones
|
1. The synovial membrane
|
Lines the joint everywhere except over the articular cartilage
|
1. This type of joint is multiaxial allowing a wide range of movement
|
Ball and socket
|
1. Ellipsoid joints
|
Are actually modified ball and socket joints
|
1. Which of the following joints is most movable?
|
Synovial
|
1. The cubital or elbow joint is an example of a _____ joint
|
hinge
|
1. Bowing the head is an example of
|
flexion
|
1. Bending the waist to one side is known as
|
Lateral flexion
|
1. Abnormal forced extension beyond normal range of motion is called
|
Hyperextension
|
1. A movement through 360 degrees that combine flexion, extension, abduction, and adduction is called
|
Circumduction
|
1. List the following structures in order from smallest to largest
|
Myofilament, myofibril, muscle fiber, muscle fascicle
|
1. Rotating the forearm so that the palm faces posteriorly is called
|
Pronation
|
1. Rotating the forearm so that the palm faces anteriorly is called
|
Supination
|
1. The medial meniscus is in the
|
knee
|
1. The muscles that hold the humeral head within the glenoid cavity are called
|
rotator cuff
|
1. Arthritis is defined as
|
Inflammation of any joint
|
1. Osteoarthritis is
.
|
The most common type of arthritis
|
1. Rheumatoid arthritis is
|
An inflammation of any joint with an autoimmune attack against joint comm
|
1. Skeletal muscle fibers
|
Possess striations
|
1. Muscle myofibrils
|
Contain myosin and actin myofilaments
|
1. Which of the following is composed of myosin molecules
|
Thick myofilaments
|
1. Which of the following is part of a thin myofilament?
|
A globular (G) actin
|
1. Troponin
|
Has a calcium-binding site
|
1. The region of the sarcomere that contains both actin and myosin myofilaments is called the
|
A band
|
A sarcomere extends from
|
One z disk to the next z disk
|
1. A sarcomere is the
|
Structural and functional contractile unit of the skeletal muscle cell
|
Actin myofilaments
|
contain strands of fibrous actin
|
1. Sarcoplasm is the
|
Cytoplasm of muscle cell
|
1. The sarcolemma is the
|
Cell membrane of a muscle fiber
|
1. The length of the resting sarcomere is
|
Longer than the length of a contracted sarcomere
|
1. The sites where a chemical substance is transmitted from the presynaptic terminal of an axon and the postsynaptic membrane of a muscle fiber is called
|
Neuromuscular junctions
|
1. Synaptic vesicles in the neuromuscular junction contain
|
Acetylcholine
|
1. When an action potential reaches the presynaptic terminal
|
Calcium ions diffuse into the presynaptic terminal through voltage-gated ion channels.
|
1. Acetylcholine is released from the presynaptic terminal by the process of
|
Exocytosis
|
1. T tubules are invaginations of the
|
Sarcolemma
|
1. T Tubules
|
Conduct action potentials deep into the muscle cell
|
1. The sarcoplasmic reticulum
|
Stores calcium ions
|
1. When the myosin head flexes into a bend, pulling the actin filament along with it, this is called the
|
Power stroke
|
1. Which of the following proteins is used to anchor the myofilaments and to help transmit the tension generated by the sarcomeres to the tendon?
|
Dystrophin
|
1. For a sprint lasting 10-40 seconds, ATP is supplied initially by:
|
The phosphagen system and then by the glycogen-lactic acid system
|
1. Rigor mortis occurs after death because
|
Cross-bridges form but cannot release
|
1. What is tropomyosin?
|
A protein found along the groove of the F-actin double strand
