1
What is a tissue?
Cells grouped together and are similar in structure and function
2
The study of the structures and arrangements of tissues
Histology
3
What are the five primary tissue types?
- Epithelium Tissue
- Connective Tissue
- Nervous Tissue
- Muscle Tissue
- Vascular Tissue
4
What is a simple epithelial tissue?
One layer or one cell thick
5
What is a stratified epithelial tissue?
Two or more layers thick
6
What are the 4 classifications of epithelium based on shape and function?
- Squamous
- Cuboidal
- Columnar
- Ciliated
7
What is a muscular tissue?
Specialized cells with the primary function of contraction
8
What are the components of muscle fiber?
- Cytoplasm
- Sarcoplasm
- Sarcolemma
9
What are skeletal muscles?
Muscle tissue attached to bones. Long, striated, cylindrical, voluntary
10
What are smooth muscles?
Muscle tissue located in the walls of hollow organs
11
What are cardiac muscles?
Specialized type of muscle. Striated and involuntary muscle tissue found in the heart
12
How do striated muscles differ from smooth muscles based on appearance?
Striated muscles have long bands and elongated nuclei. Smooth muscles have no striations and have spindle-shaped cells.
13
What are the 3 types of fibers?
- Reticular Fiber
- Elastic Fiber
- Collagenous Fiber
14
These are found in the particular ends of long bones, ventral ends of the ribs, nose, larynx, trachea, and bronchi
Hyaline Cartilage
15
Cartilage cells are also known as?
Chondrocytes
16
Loosely arranged fibroelastic tissue that consists of a clear, amorphous ground substance which holds together coagulable tissue fluid, various cells, and all the 3 types of fibers
Areolar Connective Tissue
17
Storage of fats
Adipose tissue
18
Bone part: Thin layer where other non-living mineral substances are deposited and other parts are found
Lamella
19
Outermost covering of a bone
Periosteum
20
Channels for blood vessels and nerves in a bone
Haversian or Central System
21
What is a vascular tissue?
The blood
22
What are red blood cells?
Disc-shaped, biconcave cells without nuclei. Transport oxygen and nutrients throughout the body. Contain hemoglobin
23
What are white blood cells?
Bigger blood cells that specialize in fighting pathogens
24
What are platelets?
Specialized cells for blood clotting
25
What are nervous tissues?
Receive and transmit stimuli in the form of nerve impulses to various effectors
