The Four Types of Tissue

Epithelial tissue functions to

• Provide structure and support, cushion organs, stores nutrients

• Protect the body, absorb nutrients, filter blood and secrete

• Carry impulses (messages) throughout the body

• Made of muscle fibers that relax and contract

Connective tissue functions to

• Provide structure and support, cushion organs, stores nutrients

• Protect the body, absorb nutrients, filter blood and secrete

• Carry impulses (messages) throughout the body

• Made of muscle fibers that relax and contract

Nervous tissue functions to

• Provide structure and support, cushion organs, stores nutrients

• Protect the body, absorb nutrients, filter blood and secrete

• Carry impulses (messages) throughout the body

• Made of muscle fibers that relax and contract

Examples of epithelial tissue include

• skin, digestive tract, pancreas, salivary gland

• fat cells, tendons, bone, blood

• neurons and glial cells

• skeletal, smooth, and cardiac muscle

Examples of connective tissue include

• skin, digestive tract, pancreas, salivary gland

• fat cells, tendons, bone, blood

• neurons and glial cells

• skeletal, smooth, and cardiac muscle

A cells function can sometimes be determined by it's shape. Neurons are the longest cells in the body because they

• relax and contract muscles causing movement

• carry impulses sensing and responding to the environment

• protect the body and absorb nutrients by covering/lining organs

• provide structure, support, and store nutrients

There are three types of muscle tissue

• skeletal, smooth, cardiac

• bone, smooth, cardiac

• nervous, smooth, cardiac

• connective, smooth, cardiac

Involuntary muscle tissue are not under conscious control and move without our awareness, good examples would be

• heart, intestines, biceps

• biceps, triceps, skeletal muscles

• tricerotops, bicerotops, legs

• heart, intestines, eyelids

Involuntary muscle tissue are not under conscious control and move without our awareness, the muscle types that are involuntary are

• smooth, cardiac

• smooth

• cardiac

• skeletal
