Chapter 8 Introduction to Tissue Flashcards
Embryonic development of tissue results in the there primary germ layers
🔴Ectoderm
Epidermis of skin
Tooth enamel
Outer ear
Brain and spinal cord
🔵Mesoderm
Many glands
Muscle
Kidneys
Bones
⚫️Endoderm
Lining of gastrointestinal tract
Lining of lungs
Kidney ducts and bladder
Extracellular Matrix (ECM)
Complex nonliving fluid material between cells in a tissue
Some tissue have a large amount of ECM; other tissues have hardly any
Compounds of the ECM
Water
Proteins
Glycoproteins
Proteoglycans
What are the types of body membrane?
Cutaneous membrane
Serious membrane
Mucous membrane
Connective tissue membrane
Cutaneous membrane- Skin
Covers body surface exposed to the external environment
Epithelial tissue membrane
Contains many sweat and oil glands
Serous membranes
Composed of two tissue layers
- connective tissue layer
- epithelial sheet
- secrete a thin watery fluid that lubricants organs
Pleas: surrounds each lung lines
thoracic cavity
Peritoneum: covers abdominal viscera and lines abdominal cavity
Pericardium: surrounds the heart ❤️
Mucous membrane
Epithelial membranes that lines the body surfaces opening directly to the exterior
Lining respiratory, digestive,urinary and reproductive tracts
Makes mucus that coasts and protects underlying cells, lubricates food through the digestive tract, traps contaminants, and performs other functions
Connective tissue membrane
Do not contain epithelial compounds synovial lining the spaces between bones and joints that move
Which principal type of tissue covers and protects body surfaces and lines body cavities?
epithelial
The fluid environment that fills the spaces between the cells of the body is called
extracellular matrix.
Besides water, extracellular matrix contains
Proteins and proteoglycans
Which types of tissue have a limited capacity to regenerate?
muscle and nervous
The two major categories of body membranes are
The two major categories of body membranes are
epithelial and connective. Correct
The connective tissue membranes that line the spaces between bones and joints are called _____ membranes.
synovial
Serous membrane
What is the pleura
Cover the walls and some organs of the thoracic and abdominopelvic cavities
Pleura thoracic cavity
Peritoneum Abdominal cavity
