Responsiveness, or irritability, is a necessary life function. All body cells are irritable to some extent. Because nerve cells are slightly irritable and communicate rapidly with each other via hormones, the nervous system bears the major responsibility for responsiveness. You do not need to think about responsiveness, such as involuntarily pulling your hand away from a painful stimulus. None of the statements is false. The ability of the body to maintain a relatively stable internal environment is referred to as: equilibrium. homeostasis. metabolism. negative feedback. positive feedback.

Because nerve cells are slightly irritable and communicate rapidly with each other via hormones, the nervous system bears the major responsibility for responsiveness.

The effector is usually a type of sensor that monitors and responds to changes in the environment. Information in homeostatic control mechanisms flows from the receptor to the control center via the efferent pathway. The control center determines the set point at which a variable is to be maintained, analyzes the information it receives, and then determines the appropriate response or course of action. Information flows from the control center to the effector along the afferent pathway. A and B.

the position in which the body is erect, facing front with feet parallel and arms hanging at the sides with the palms facing forward.

lateral


Which of the following statements regarding feedback mechanisms is/are FALSE?


Blood clotting is an example of a typical negative feedback mechanism.

Positive feedback mechanisms tend to increase the original stimulus and to push the variable farther from its original value. In negative feedback mechanisms, the net effect of the responses to the stimulus is to shut off the original stimulus or reduce its intensity. Positive feedback mechanisms control infrequent events that occur "explosively." Blood clotting is an example of a typical negative feedback mechanism. When the body is subject to physical trauma, such as in an automobile accident, which organs are the most vulnerable to injury (homeostatic imbalance)?

armpit.


Metabolism is: a broad term that refers to all the chemical reactions that occur in the body. a term that refers to the chemical reactions where larger structures are made from smaller ones (synthesis). the term that refers only to the process of breaking down ingested food into simple molecules that can then be absorbed into the blood for delivery to all body cells. a term that refers to the chemical reactions where large molecules are broken down into smaller ones. the ability to sense changes (stimuli) in the environment and then to react to them.

Tissues consist of groups of similar cells that have a common function. Atoms are the building blocks of matter, and combine to form molecules. The digestive system, reproductive system, and endocrine system are examples of organs. An organ is made up of two or more tissue types. Organ systems make up the living body or the organism. Which of the following is NOT true of a sagittal plane?

A sagittal section divides the body into anterior and posterior parts.

A sagittal section is a cut made along the A coronal plane divides the body into lengthwise, or longitudinal, plane of the anterior and posterior parts. body dividing the body into right and left parts. A sagittal section divides the body into anterior and posterior parts. A midsagittal plane divides the body into equal right and left parts. A median plane is another name for a midsagittal plane. Both the sagittal and coronal planes represent a cut made along a lengthwise plane.



Which of the following is NOT true of the skeletal system?

Bones are not necessary for efficient movement.

The skeletal system consists of bones, cartilages, ligaments, and joints. Bones are not necessary for efficient movement. The skeletal system has a protective function.
