Tissues Part 3 - Connective, Muscle and Nervous

Question 1

Main role of connective tissue?

Answer 1

Supports body structures; typically anchors epithelial tissue to itself

Question 2

What are the four types of connective tissue?

Answer 2

Connective Tissue Proper, Cartilage, Bone, Blood

Question 3

What cell do the four types of connective tissue arise from?

Answer 3

Mesenchyme Cell

Question 4

Functions of connective tissue include?

Answer 4

Binding and support, protecting, insulating, storing reserve fuel (i.e. calcium in the bones), Transporting substances

Question 5

What are most connective tissue made of?

Answer 5

Ground substances + fibres

Question 6

What is ground substance? What role does it play in connective tissue?

Answer 6

Background material between cell and fibre; fluid - helps bind structures together

Question 7

What are the fibres in connective tissue? What purpose do they have?

Answer 7

Reticular, Collagen and Elastic fibres and they all have a role of providing strength to the tissue.

Question 8

In order of strength from least to greatest, list the fibres

Answer 8

Elastic, Reticular and Collagen

Question 9

Why is extracellular matrix so important in connective tissue?

Answer 9

Connective tissue is the only tissue mainly composed of extracellular matrix (non-living cells); ground substance + fibres make extracellular matrix

Question 10

If ground substance and fibres make the non-living cells what do the rest of the components make?

Answer 10

Made up of living cells - i.e. mast cells, eosinophils, neutrophils, adipocytes, macrophages, fibroblasts, and plasma cells

Question 11

What is the function of connective proper tissue?

Answer 11

Binding (epithelial to connective), resists tensions/mechanical stress (i.e. in ligaments), fat storage, provides reservoir for water and salts

Question 12

What is the most common fibre in connective tissue?

Answer 12

Collagen fibre

Question 13

How many types of connective tissue fibres are there?

Answer 13

6 different types (vary in density and fibre type)

Question 14

Where can connective tissue proper be found?

Answer 14

Adipose, Under (supporting) epithelia, Ligaments (connect bones)

Question 15

What are the main functions of connective tissue in cartilage?

Answer 15

Resists compression, cushions and supports body structures

Question 16

Why is there cartilage between two bones

Answer 16

To keep the bones from rubbing against each other; lubricating them

Question 17

Purpose of high amounts of water in the cartilage?

Answer 17

Resisting compression while acting as a lubricant for the cartilage surrounding it; helps cartilage keep sponginess

Question 18

What are the three types of connective tissue: cartilage?

Answer 18

Hyaline, Elastic, Fibrocartilage

Question 19

How do the types of connective tissue: cartilage vary from one another?

Answer 19

Diff. levels of strength and elasticity

Question 20

Which connective tissue cartilage is most common in the body? An example of where you might find this type of cartilage?

Answer 20

Hyaline is the most common; found in ligaments

Question 21

What is elastic cartilage?

Answer 21

More elastic properties; allow for movement of the body parts that need to bend

Question 22

What is fibrocartilage?

Answer 22

Toughest cartilage made of strong fibres; found in some joints and allows for more mobility than hyaline

Question 23

What is connective tissue bone used for?

Answer 23

Form connective bases of the body

Question 24

Functions of connective tissue bone?

Answer 24

Resist compression and tension & acts as support for the body

Question 25

Example of how bone resists tension

Answer 25

When muscles contract they pull on the bone and the bone resists a lot of that tension

Question 26

What are the tissues bone classified into?

Answer 26

Compact bone and spongy bone

Question 27

What are the functions of connective tissue blood?

Answer 27

Fluid tissue & transporting (O2, CO2, nutrients, wastes, hormones)

Question 28

Features of muscle include?

Answer 28

High cell concentration, Highly vascularized (lots of blood vessels), responsible for body movement

Question 29

How many types of muscles are there and what are they?

Answer 29

Three types; cardiac, skeletal and smooth

Question 30

Feature of skeletal muscle that smooth and cardiac do not possess?

Answer 30

Skeletal muscles move voluntarily

Question 31

Where would you find smooth muscle?

Answer 31

Covering organs and blood vessels

Question 32

What comprises the Nervous system?

Answer 32

Brain, Spinal Cord, Nerves

Question 33

What are the two cell types of nervous tissue?

Answer 33

Neurons & Supporting Cells
