a tissue made of cells that form a barrier between a living thing Epithelial Tissue a tissue made of cells that form a barrier between a living thing and the tissue’s outside environment Lines or covers... examples of include skin intestines lungs

Nervous Tissue the tissue of the nervous system which is made of neurons and their supporting cells In other words... Brain and nerve cells

Connective Tissue A tissue that connects and supports other tissues holds organs in place ligaments and tendons

Muscle Tissue A tissue that can contract (squeeze) and relax to produce movement smooth skeletal cardiac

Identify the tissue

Body cavity any cavity that holds and protects organs like throat and lungs, abdominal and pelvic

Axial Skeleton bones of the skull and vertebrae Appendicular Skeleton arm and leg bones

bone marrow soft tissue inside bones where the red and white blood cells are made

Periosteum tough, fibrous tissue that covers bones and has blood vessels that supply nutrients to bones and nerves

Haversian Canal found in compact bone tissue and as blood vessels This canal is how blood gets from the marrow to the circulatory system where blood flows throughout the body

Osteocyte a bone cell

Osteoporosis a condition where bones break easily because they are weak and skinny

Joint Where two or more bones meet 5 kinds of Joints Ball and socket Gliding Pivot Hinge Fixed Where two or more bones meet

ball and socket gliding hinge pivot fixed

Ligament This tissue holds the ends of the bones together. Ex:

Tendon this tough connective tissue attaches muscles to bones or other body parts Ex

Flexor this muscle bends body parts

Extensor A muscle that extends or straightens

Epidermis The outer layer of a plant or animal

Keratin flexible but hard proteins that make up hair, feathers, nails and horns

Melanin the pigment that gives skin its color. This pigment also protects the epidermis (skin) from harmful ultraviolet radiation

Dermis 2nd layer of skin. It is under the epidermis

Hair follicle a hole in the skin that surrounds a hair and the root of a hair

Subcutaneous Tissue cells that are located under the skin

Sebum an oily substance made by the sweat glands

Key chapter concepts Cells are grouped into 4 kinds of tissue: ·epithelial ·nervous ·connective ·muscle (3 kinds- smooth, skeletal, cardiac) Body organs contain more than 1 type of tissue ex: lungs- smooth muscle and epithelial

The Skeletal System: The skeleton ·supports the body ·provides protection ·allows movement ·stores nutrients ·makes blood There are 206 bones. The skeleton is divided into 2 parts ·axial (skull, vertebra (spine), ribs, and sternum ·appendicular (everything else) Bones start as cartilage (like your ear) and then harden as you get older with calcium and minerals There are 5 kinds of joints: ·ball and socket (hip, shoulder) ·gliding (hand) ·pivot (elbow) ·hinged (knee and elbow) ·fixed (jaw)

Bone marrow: Muscular System: ·red and white blood cells are made in the marrow of long bones ·Haversian Canals and the Periosteum transport blood ·from the bone marrow to the circulatory system Muscular System: ·Tendons attach muscles to bone ·Ligaments attach bone to bone

Skin, Hair and Nails The skin has 2 layers ·epidermis ·dermis ·Subcutaneous tissue holds skin to organs ·Hair and nails are made from the epidermis layer ·Most skin problems are caused from damage to the top layer of skin (epidermis)
