Chapter 2 Flashcards
What is the structural organization of the body?
Cells –> Tissues –> Organs –> Systems
What are the major parts of a cell?
- Chromosomes
- Nucleus
- Cell Membrane
- Cytoplasm
- Mitochondrial
- Endoplasmic Reticulum
What is Karyotyping? When is it used?
- Karyotyping is a photograph of an individual’s chromosomes arranged by number and structure.
- Determines whether the chromosomes are normal or not, especially for pregnant women
What is cytoplasm?
It includes all materials outside the nucleus, but still contained within the cell membrane
What are the mitochondria?
- Small, sausage-shaped bodies that produce energy by burning food.
- “The power plant.” Produces ATP
What is endoplasmic reticulum?
Network of canals within the cytoplasm of the cell. Large proteins made here.
What is the cell membrane?
Structure surrounding and protecting them cell. Regulates what comes in and goes out.
What is DNA?
Chemicals found within each chromosome.
What are genes?
Regions of DNA within each chromosome.
What is anabolism? (Study Guide)
- Process of building up large proteins from small proteins called amino acids.
- Build UP!
What is catabolism?
- Process whereby complex nutrients are broken down to simpler substances and energy is released.
- Break DOWN!
What is metabolism?
- Total of the chemical processes in a cell.
- Catabolism + anabolism
What is the nucleus?
- Control center of the cell
- Contains the chromosomes
- Tells the cells what to do (activities)
Does catabolism or anabolism occur in mitochondria?
Catabolism
What are the 4 different types of tissues?
- Epithelial Tissue
- Muscle Tissue
- Connective Tissue
- Nerve Tissue
What is a histologist?
The term for a scientist who specializes in the study of tissue
Which tissue conducts impulses all over the body?
Nerve
Example of what type of tissue include fat and cartilage?
Connective
What tissue forms the linings of internal organs and the outer surface of the skin?
Epithelial
What tissues contains the voluntary and involuntary muscles?
Muscle Tissues
What are adipose tissues?
Collection of fat cells
What is a cartilage?
Flexible connective tissues often attached to bones at joints.
What is the larynx?
- Voice box
- located at the upper trachea
- part of the digestive system
What is the pharynx?
- Throat
- Passageway for food
- Part of the digestive system
