Question

question 22 1 pts muscle tone is maintained by positive feedback mechanisms. negative feedback mechanisms. both positive and negative feedback mechanisms. none of the above. question 23 1 pts the joints between the articulating surfaces of the vertebral processes are classified as what type of joint? hinge ball and socket gliding immovable question 24 1 pts synarthrotic joints are freely movable. slightly movable. immovable. freely movable and slightly movable.

Explanation:

• Question 22: Muscle tone is maintained by a continuous, low - level state of muscle contraction which is regulated by negative feedback mechanisms that adjust muscle tension. Positive feedback typically amplifies a response and is not involved in maintaining muscle tone.
• Question 23: The joints between the articulating surfaces of the vertebral processes are gliding joints. Gliding joints allow for side - to - side and back - and - forth movement. Hinge joints allow movement in one plane (like the elbow), ball - and - socket joints allow for multi - directional movement (like the shoulder), and the vertebral joints are not immovable.
• Question 24: Synarthrotic joints are immovable joints. Examples include the sutures in the skull. Freely movable joints are called diarthroses, and slightly movable joints are called amphiarthroses.

Answer:

Question 22: negative feedback mechanisms.
Question 23: gliding
Question 24: immovable
