Anatomy Introduction Quiz: Everything but the Directional Terms, Cavities and Body Planes

Anatomy, physiology, the orders of the levels of organization, body systems with life functions, homeostatic mechanisms, negative and positive feedback

Anatomical position provides a fixed reference point for all directional terms

What is the importance of having an anatomical position?

A forward position where you stand up head straight and arms by your side with the palm of your hands facing forward

What is an anatomical position?

Anatomy deals with the structure of the human body

What is the definition of anatomy?

Physiology deals with the functions of the human body

What is the definition of physiology?

Cell

What is the main unit of living things?

Atoms-molecules-organelles-cells-tissues-organs-organ system-organism

Which of the following list is in the order of increasing levels of complexity?

Tissues are formed by groups of cells that perform similar functions

What are tissues formed by?

Cells are made up of organelles which provide individual functions within a cell

What are cells made up of?

Bringing the system back to a stable state

What is the definition of negative feedback with the homeostatic mechanism?

Body temperature regulation senses change in temperature and initiates responses to reverse that change, maintaining a stable temperature

What is an example of negative feedback with the homeostatic mechanism?

Causing rapid progression toward a specific goal

What is the definition of positive feedback with the homeostatic mechanism?

During childbirth, the release of oxytocin and contractions trigger the release of more oxytocin to intensify the process until the baby is born

What is an example of positive feedback with the homeostatic mechanism?

Responsiveness is the ability to sense and react to changes, which is controlled by the nervous and endocrine systems

How is responsiveness a life function that involves a body system?

Digestion is the life function performed by the digestive system to break down food into nutrients

How is digestion a life function that involves a body system?

Your endocrine system uses hormones to control your metabolism, the process that provides your body with energy

How is metabolism a life function that involves a body system?

Excretion is the life function of removing metabolic wastes from the body. It is performed by the excretory system

How is excretion a life function that involves a body system?

Reproduction is a life function managed by the reproductive system. It works by combining genetic information from two individuals in order to produce the future generation

How is reproduction a life function that involves a body system?

The endocrine system uses hormones as chemical messengers in order to increase growth, cell size and number

How is growth a life function that involves a body system?

Movement, as a life function, involves the muscular, skeletal, and nervous systems to produce both internal and external movement

How is movement a life function that involves a body system?

Firstly the integumentary system is the system that helps maintain boundaries in the body by providing a physical barrier with the skin. Protecting against injury or UV radiation

How is maintaining boundaries a life function that involves a body system? 

The integumentary system is the body’s outer layer and made up of skin, hair, and nails, its main role is to serve as a physical barrier 

What is the definition of the integumentary system?
