The central pattern generator (CPG) . a. monitors changes in the chemical composition of the cerebrospinal fluid (CSF) b. is responsible for generating the cycle of inspiration and expiration c. is located in the cortex of the brain used to be called the pneumotaxic centerd. is located in the cortex of the brain

The correct answer is:

is responsible for generating the cycle of inspiration and expiration (b.)

Explanation:

some crucial an important locomotive behaviors like walking, swimming, flying and crawling are described as cyclic (repetitive). Other essential metabolic and homeostatic functions like respiration, breathing (inspiration and expiration), gut movement, chewing and heartbeat have their repetitive rhythmic patterns controlled basically by central circuits called Central Patter Generators (CPGs). It describes essentially, the generation of rhythmic outputs without rhythmic inputs. Other activities such as defecating, urinating and ejaculating are also controlled by CPG. Although input in these activities do not come actively from higher brain centers, they still require modulatory inputs, and these inputs are not fixed. There are two requirements for the CPG to be classified as a rhythmic generator, and they include; 1. two more processes that sequentially increase and decrease must interact, and 2; as a result of this interaction, the system returns to its starting point.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
