Contains many different types of cells.

14

What are the three types of connective tissue?

Loose connective tissue
Dense connective tissue
Cartilage

15

What part of the body would you find loose connective tissue?

Made up of fibers and many cell types in a gelatinous matrix.
Found in skin and surrounding blood vessels, nerves and organs

16

What part of the body would you find dense connective tissue?

Bundles of parallel collagen fibers and fibroblasts.
Found in tendons and ligaments.

17

What is cartilage made of and where would you find it in the human body?

Made of collagen and elastin fibers embedded in a matrix of glycoprotein and cells called chondrocytes found in small spaces.
Found in ear, nose, ends of long bones, pelvis, skull and vertebral discs.

18

What are the three types of muscle tissue?

Striated/voluntary/skeletal muscle
Smooth/involuntary muscle
Cardiac muscle

19

Where do you find nervous tissue?

In the brain, spinal cord and nerves that control movement, transmit sensation and regulate many body functions.

20

How many types of cells is nervous tissue made of?

Two types.
Neurons and Neuroglia
