Which statement best describes the physiological role of the endocannabinoid system in learning extinction?
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.
Which statement best describes the physiological role of the endocannabinoid system in learning extinction?
(a) Activation of the CB1 receptor increases learning extinction;
(b) Activation of the CB1 receptor decreases learning extinction;
(c) Blockade of the CB1 receptor increases learning extinction;
(d) Blockade of the CB1 receptor decreases learning extinction.
Extinction learning is the phenomenon by which animals with advanced mental capabilities (like dogs, humans, etc) learn to stop responding to a conditioned stimulus, after the stimulus have stopped been followed by an expected outcome.
Suppose you trained a dog from its childhood to come to you to feed whenever you ring a bell. So after ringing the bell, you used to feed the dog. But for a few weeks or even months, you rang the bell but did not feed the dog after. Gradually the dog will stop coming to you whenever you rang the bell. This phenomenon by which the dog learned to stop responding to the bell (the stimulus) , after a period in which the bell was not followed by food (the expected outcome), is what is called extinction learning.
