What type of tissue has the highest degree on contractility?
Muscle tissue
Are muscle tissues fast or slow to heal?
Slow
What often forms in muscle tissues when injured?
Scar tissue
What are 3 types of muscle tissues?
- Skeletal
- Cardiac
- Smooth
Are skeletal muscles voluntary or non-voluntary?
Voluntary
How do bones attach to muscles?
Through tendons
What do you see when you look at muscles under the microscope?
Striations
Fibres
Individual cells
What do skeletal muscles help with?
Movement
Are cardiac muscles voluntary or non-voluntary?
Non-voluntary
What do cardiac muscles form?
The walls of the heart
What do cardiac muscles produce?
Regular, non-voluntary contractions in order to create a heartbeat
What is the appearance of cardiac muscles? (2)
- Faint cross striations
2. Intercalated disks
Intercalated disks
Thicker dark bands
Is smooth muscles voluntary or non-voluntary?
Non-voluntary
What is the appearance of smooth muscles? (2)
- Smooth
2. No cross striations
What do smooth muscles form? (2)
- Walls of blood vessels
- Hollow organs
- eg. intestines, stomach
What do nervous tissues provide? (2)
- Rapid communication between body structures
2. Controls body functions via transmission of nerve impulses
What 2 cell types do nervous tissue consist of?
- Neurons
2. Glia
Neurons
Nerve cell
What makes up a neuron? (3)
- Cell body
- Axon
- Dendrite
What does the axon do?
Carries nerve impulses away from the cell body
What do dendrites do?
Carry nerve impulses toward the cell body
What does glia mean?
Glue
What do glial cells do? (2)
- Support cells
2. Connect cells
What part of the nerve tissue is harder to repair if damage occurred to it?
The neuron
