All about the 3 types of tissues (inclusive? nope)

Question 1

What are the 3 types of tissues?

Answer 1

1. Epithelial tissue - epithelium
2. Connective tissue
3. Muscle tissue

Question 2

Teeny info about epithelial tissue?

Answer 2

1. Refers to sheets of cells that cover exterior surfaces of the body
2. Lines internal cavities and passageways
3. And forms certain glands

Question 3

Info about epithelial tissue?

Answer 3

• This tissue type forms the lining of the body and organs (endothelium)
• Cells are closely packed together and may have cilia, they have a basement membrane connecting them
• Can be simple (one layer) or compound (several layers)
• Can have several shapes:
  Columnar (tall and thing) e.g. intestines
  Squamous (flat) e.g. blood vessels
  Cuboidal e.g. kidneys

Visuals:
Squamous: It’s quite literally flat so, ye. Perhaps a bunch of eyes shaped all together as a cube, remember it’s more flat
Cuboidal: Just like squamous but not rlly flat like that. I’d say there’s more in a row too
Ciliated columnar: So it’s tall and thin ofc. In addition, “ciliated”, so look at the top of it too

Question 4

Teeny info about connective tissue?

Answer 4

1. Binds the cell and organs of the body together
2. Functions in the protection, support, and integration of all parts of the body

Question 5

Info about connective tissue?

Answer 5

• These connect different tissue types and organs together and also includes the skeleton and blood
• Cells are often far apart and from each other and connected by a fluid, solid, or semi-solid substance (the extracellular matrix)
• For example, Osteocytes, the bones are connected by a solid substance formed mostly of calcium

Visuals:
Well it’s a fluid/substance so, idk reminds me of the cohesion of H2O

Question 6

Teeny info about muscle tissue?

Answer 6

1. Excitable, responding to stimulation and contracting to provide movement
2. Occurs as three major types: Skeletal (voluntary) muscle, Smooth muscle, Cardiac muscle in the heart

Question 7

Info about muscle tissue?

Answer 7

• Muscle fibres are only cells which can contract and relax, this action causes the muscle tissue as a whole to contract and relax
• Muscle tissues appears striated (stripy)
• 3 main types: smooth, skeletal and cardiac
• Smooth = muscles you cannot control, found in digestive system and blood vessels
• Skeletal = muscles used to move your skeleton about a joint
• Cardiac = muscles found in your heart

Visuals:
Skeletal: Bones ig? with them dark slabs around
Smooth: A bunch of mari’s, if u know u know
Cardiac: lowkey looks like the trachea but obviously muscle stylated
