Chapter 9 Part 2 Flashcards
Describe 3 features of connective tissue
Most abundant tissue in the body
Most widely distributed tissue in body
Multiple types determined by structure of matrix and fibres
Extracellular matrix is _________ in most connective tissue and determines ________
Predominant
Determines physical characteristics
3 types of connective extra cellular matrix
Fluid, gel or solid matrix
Matrix can be made of ____- or ______ fibres
Collagenous and or elastic
4 functions of connective tissue
- connects, binds and supports structures
- protects and cushions organs and tissues
- insulates
- transports substances
4 classifications of connective tissue
- Fibrous
- Bone
- Cartilage
- Blood
3 types of fibrosis connective tissue
Areolar, adipose/ fat, dense fibrous
7 major types of connective tissue to know
Areolar Adipos Dense fibrous Bone Cartilage Blood Hematopoietic
2 feature of loose fibrous (areolar) connective tissue
Most widely distributed of all CT.
Glue that holds organs together
2 features of adipose connective tissue
Lipid storage is primary function,
Produces leptin
A3 features of dense fibrous connective tissue
Densely packed fibres within matrix
Collagenous and/or elastic fibers
Strong and flexible
5 features of bone (connective tissue)
One of the most specialized types of CT
Matrix is hard and calcified
Forms structural building blocks called osteosarcoma
Circular structure
Function is support, protection, movement, mineral storage, and supporting hematopoietic tissue
3 features of cartilage (connective tissue)
Cells are chondrocytes
Avascular
Matrix is consistency of a firm plastic/rubber or gristle like gel
3 features of blood (connective tissue)
Most unusual type of CT
Matrix is fluid
Functions are transportation, body temp , ph and immunity
5 features of Hematopoietic tissue (cancellous bone)
Blood like connective tissue found in red marrow cavities
Found in bones, spleen, tonsils, lymph nodes
Form blood and lymphatic cells
Important in immunity
Called spongy bone due to appearance
2 features of bone tissue
Have the highest degree of contractibility
Slow to heal
3 types of muscle tissue
Smooth, skeletal and cardiac
Skeletal muscle can also be called
Striated of voluntary
Skeletal muscle attaches to bone via
Tendons
3 features of cardiac cells
Form wall of the heart
Produce regular involounary contractions of cardiac muscles
Has faint cross strait ions and thicker dark bands called intercalated disks
Smooth muscle can also be called
Visceral, non-striated or involountary
3 features of smooth muscle
Involuntary control, appears smooth, forms walls of blood vessels
Function of the nervous tissue
Provides rapid communication between body structures and control of body functions via transmission of nerve impulses
Nervous tissue consists of what two types of cells
Neurons and glia
3 parts of a neutron
Cell body
Axon (carries nerve impulses away)
Dendrites ( carry nerve pulses towards the cell body)
Another name for glia, what glia means and what they do
Neuroglia
Glue
Supportive and connecting cells
