Hawaii - Cells

  • The nerve cell's in our brain stretch out their dendrites like ladies practicing yoga. They whisper to other cells in the nervous system carry messages through an electrochemical process. The human brain has approximately 100 billion neurons. Neurons are similar to other cells in the body because: Neurons are surrounded by a cell membrane. Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other organelles. Neurons carry out basic cellular processes such as protein synthesis and energy production. However, neurons differ from other cells in the body because: Neurons have specialized extensions called dendrites and axons. Dendrites bring information to the cell body and axons take information away. Neurons communicate with each other through an electrochemical process. Neurons contain some specialized structures (for example, synapses)
  • Neurons are the basic building bricks for the entire human body. A neuron is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. This chemical signaling is called a synapse when it sends messages to other neuron cells. The human body is made of trillions of cells. They bind together creating walls within the tissue. They send messages from your brain to the muscles and tell them to move. Without this giant electrical system our world would be motionless.
  • The lackadaisical cell works quietly like the gears of a machine working together. The cell theory is made up of 3 basic rules. 1) All living thinks are composed of cells. 2) Cells are made from other cells. 3) Cells are the basic unit of structure and function. My drawing of the cells show the cells all clumped up in a pile called a tissue. The cell is often referred to as a brick and the tissue is referred to as a brick wall. Red blood cells help with the bloodstream and are said to help fight bacteria that enter the body.
  • The red blood cells floating lazily within the tissue of all living things is like the tiny jelly beans pouring slowly into a giant jar. Did you know that your blood contains more red blood cells than any other kind of cell? These blood cells have a disk-like shape with pinched-in center. They are produced in bone marrow. Red blood cells carry oxygen throughout the human body. They may seem slow moving but they are extremely important to keeping our much needed blood healthy and flowing to each of the organs in the body that need it to function.
  • The colorful beach balls hug peacefully in their cozy home waiting for minerals and stress. According to the cell theory all living things are composed of cells, all cells are produced from other cells, and cells are the basic unit of structure and function in living things. The image is an osteocyte cell which is a mature bone cell. It lies in the lacunae of the bone tissue and is one of three bone cells in the tissue. Osteocytes help control the mineral balance of the body and responds to stresses formed by physical activity. These cells like many others in make their self at home in our body patiently waiting to do their very specific job.
  • Like the fan belts on the motor of my cherry red Nissan, the long muscle cells stretch out smoothly waiting for communication from the brain.
