Lecture 19: Anatomy and Physiology I (tissues/organ systems) Flashcards
What is anatomy?
The study of body structure
What is a cell?
The basic unit of a living organism
What is tissue?
Integrated group of cells working together
What are 4 main tissue types?
- Muscle tissue
- Connective tissue
- Nervous tissue
- Epithelial tissue
What is muscle tissue?
Tissue used for movement
What is smooth muscle?
Muscle that is not striated and is involuntary(internal organs)
What is skeletal muscle?
Muscle that is striated and voluntary
What is cardiac muscle?
Muscle that is striated and is involuntary
What is connective tissue?
Connections where cells are imbedded in extracellular matrix
What are the 6 types of connective tissue?
- Loose connective
- Dense/fibrous
- adipose
- blood
- cartilage
- bones
What is loose connective tissue?
Where cells and fibers are embedded in semifluid matrix. An example is areolar tissue that is internal cushioning.
What is dense/fibrous connective tissue?
Tissue where collagen fibers are arranged in bundles. Some examples are tendons and ligaments
What is adipose?
Adipocytes(fat cells) that store tryglicerides
What is blood?
Blood cells in a liquid matrix
What is cartilage?
Chondrocytes in a collagen matrix
What are bones?
Osteocytes(bone cells) that are found in a collagen matrix with calcium added.
What are example of muscle tissue?
- smooth muscle
- skeletal muscle
- cardiac muscle
What is nervous tissue?
Tissue that relays information through neurons
