TYPES OF ANIMAL CELLS

Specialized cell

Specific type of cells that has featured allowing them to carry out a function.

Skin cells

Body first line of defense. Consist of keratinocyte and melanocyte

Keratinocyte

Make up 90% of skin cells, and produce proteins called KERATIN.

Keratin

A protein help make skin and effective layer of protection for body (nails and hairs).

Melanocytes

Produces melanin, found underneath keratinocyte. the more melanocyte to have in your skin the darker your skin is.

Melanin

Colors the skin,

Red Blood Cells

Make up 99.9% of all blood cells. Respond for delivering oxygen from lungs to all body.

Hemoglobin

Colors blood red, carries oxygen molecules

White blood cell

Help battle infections and protect immune system.

Granulocytes

Have granules, when released it can destroy pathogens.

Muscle cells

Long stubular cells for moving organisms limbs and organs.

Skeletal muscle cells

Found attached to bones, regulates body temp., generate movement and support body posture.

Cardiac muscle cells

Muscular tissue of the heart. Circulation of blood and contracts involuntarily and controlled by ANS.

Autonomic Nervous System

ANS

Smooth muscle cells

Found in lining of hollow organs like stomach and responsible for involuntary movements such as peristalsis in Digestive tract and regulating blood flow.

Nerve cell

Neurons, maintain cells in nervous system

Dendrites

Receive incoming signals from other neurons(receiving antenna)

Axons

Transmit signals away from the neuron to other cells (sending cable)

Sex Cells

For sexual reproduction, contains half the number of chromosomes of a normal body.

Sperm Cell

Small and motile, has tails enables them to swim to fertilize the egg.

Egg Cells

OVA, large and non-motile, provide necessary nutrients and resources for development of embryo after fertilization.

Vertebrates

Animals have spine or backbone and skull. More developed brain and internal skeleton.

Endoskeleton

Internal support system made of bone or cartilage.

Mammals

Have fur or hair and gives birth to young and feed with milk

Birds

Covered with feathers and lay eggs. Have beaks and mostly can fly using wings.

Fish

Animals that live in water, and breath through gills. Has find for swimming and scales as coverings.

Amphibians

Can live both land and water and lay eggs. Have moist skin and start breathing through gills before developing into lungs as adults.

Reptiles

Covered by dry, scaly skin. Lay eggs on land and breath through lungs for their whole lives.

Invertebrates

Animals neither develop nor retain vertebral column, evolved from notochord.

Vertebratus

Latin for jointed or having a backbone
