Milady Chapter 2 (14th Edition)
What are the three reasons that cosmetologists should have a thorough understanding of anatomy and physiology?
1. Scalp manipulations, facials, and pedicures are all common cosmetology procedures that rely on an understanding of human anatomy. 2. Recognising healthy hair, skin, and nails is an important infection control step, as is identifying conditions that require referral to a healthcare professional. 3. Working with the bones of the face and skull contributes to flattering haircuts, hairstyles, and makeup applications.
What does the protoplasm of a cell contain?
A cell is made up of protoplasm, in which nutrients, mineral salts, and water are present.
Cells are the basic units for all what?
All living things. Bacteria, plants, animals, humans.
Describe the two types of metabolism, the chemical process in which cells convert nutrients to energy.
Anabolism - the process of simple molecules combining to form a complex molecule. Anabolism requires energy. Catabolism - the process of breaking complex molecules down into simple molecules. Catabolism releases energy.
What is the difference between the study of anatomy and the study of physiology?
Anatomy is the study of human body structures, how the body parts are organised, and the science of the interconnected structures of organisms, or of their parts. Whereas, physiology is the study of the functions or activities performed by the body's structures.
Where is the cytoplasm located and what is it's function?
Cytoplasm is the watery fluid that surrounds the nucleus. It provides a structure for the cell parts so they can move freely within the cell membrane. It contains enzymes that help digest and break down other molecules for food.
When it comes to observing possible illnesses or infections in a client, what is always outside of a cosmetologist's scope of practice?
Diagnosing or treating any illness is never within a cosmetologist's scope of practice.
What are the three parts of the body that cosmetologists focus on? What parts of the body do cosmetology services affect?
Hair, skin, and nail health. Cosmetology services affect the skin; muscles; nerves; circulatory system; and bones of the head, face, neck, shoulders, arms, hands, lower legs, and feet.
Where is the cell membrane located and what is it's function?
The cell membrane is the thin layer of tissue that surrounds the cell. It protects the interior of the cell from its surroundings and is semipermeable, meaning it allows certain substances to enter the cell.
Where is the nucleus located and what is it's function?
The nucleus is the specialised structure in the center of the cell. It controls the growth and reproduction of the cell and also contains the cell's genetic material.
The process of cell _________ is called _________. It occurs when the cell _________ into _________ identical _________ cells. Cells require _________ conditions to _________ and reproduce. These conditions include adequate _________ supply, oxygen, water, suitable _________, and the ability to _________ waste.
The process of cell reproduction is called mitosis. It occurs when the cell divides into two identical daughter cells. Cells require favourable conditions to grow and reproduce. These conditions include adequate food supply, oxygen, water, suitable temperatures and the ability to eliminate waste.
