SCIENCE- CHAPTER 15

4 types of tissues in the human body

Epithelial, Connective, Nerve, Muscle

Levels of organization (from least to greatest)

1. Cells

2. Tissue (Muscular, Connective, Nerve, Epithelial)

3. Organ

4. Organ system

Muscle tissue

The only tissue that can contract and shorten.

Examples of muscle tissue

Skeletal, smooth, cardiac

Connective tissue

Provides support and connects all the parts.

Examples of connective tissue

Bones, Blood, Fat

Nerve Tissue

Carries messages back and forth from your brain to your spinal cord and all your body.

Examples of nerve tissue

Brain, spinal cord, nerves

Epithelial tissue

Form a protective surface on the outside of your body.

Examples of epithelial tissue

Skin, cavities, glands

Organ made up of all 4 kinds of tissue

Heart

5 main functions the skeletal system

1. Provides shape

2. Allows movement

3. Protects organs

4. Helps produce blood cells

5. Helps Store chemical substances

Bone is a ______ tissue

Living

Mature bones generally contain a cavity filled with _____________________

Marrow and blood vessels

To which group of tissue does the bone belong to?

Connective tissue

What kind of tissue transports information to other parts?

Nerve tissue

Which group of tissues does the spinal cord belong to?

Nerve tissue

Cardiac muscle tissue is found only in the?

Heart 🫀

Skeletal muscle tissues are found mainly in muscles that are…?

Controled voluntary

Muscles always work in pairs (True or false)

True

How many bones does the human body have?

206 bones

Which connective tissues connect the skeletal system?

bones, ligaments, tendons

The vertebral column contains __ bones called ______?

26, vertebrae

Places where cartilage may be found

Nose, ears, bone, lungs

Bones

Structure that makes up the body’s skeleton

Ligaments

Stringy connective tissue that holds bones

Tendons

Connects muscle to bones

Part 1 of a Skeleton

Head to the hips. Skull, sternum, clavicle, backbone, ribs

Part 2 of a Skeleton

Arm, legs, hips, hands, shoulders

Many bones are made of?

Cartilage

Cartilage

Tissue that supports and gives shape

Functions of the cartilage

1. Cushion bones against joints

2. Provide slippery substance so bones don’t rub against each other

STRUCTURE OF BONES

Cells, living and connective tissues, marrow, blood vessels

2 types of marrows

Yellow, Red

Yellow Marrow contains

Fat, blood vessels

Red Marrow contains

Red blood cells

How many muscles does the human body have?

600

3 types of muscle tissue

Cardiac, skeletal, smooth

Describe cardiac muscle

Rhythmic contraction and blood pumping function

Describe smooth muscle

Control breathing, blood pressure, digestive movements

Describe skeletal muscle

Voluntary movement, connected to bones

Cylinder-shaped cell

Muscle fiber
