Biology And Anatomy and physiology and chemistry

• The brain is the control center of the nervous system.
• The spinal cord connects the brain to nerves throughout the body.
• Nerves are bundles of nerve fibers that transmit messages between different parts of the body.
• Neurons, or nerve cells, are specialized cells that transmit electrical impulses along their axon.
• Neurons, or nerve cells, are specialized cells that carry electrical impulses along their length.
• Sensory neurons carry information from sensory receptors (such as eyes, ears, skin) to the central nervous system.
• Motor neurons carry signals from the central nervous system to muscles and glands.
• Sensory neurons detect stimuli from the environment and send signals to the central nervous system (CNS).
• Sensory neurons carry information from sensory receptors to the central nervous system (CNS).
• Motor neurons carry signals from the CNS to muscles and glands.
• Interneurons are located within the CNS and relay signals between other neurons.
• Motor neurons receive information from the CNS and trigger muscle contractions or glandular secretions.
• Interneurons relay information within the CNS and coordinate responses to sensory input.
• Interneurons are located within the central nervous system and relay information between other neurons.
• Interneurons connect neurons within the CNS and process information.
• The four basic organic macromolecules produced by anabolic reactions are ______(polysaccharides),_____ acids, P____, and L____. (please fill in the blank with commas example polly, flower etc..)

  carbohydrates, nucleic acids, proteins, lipids
• What are lipids?

  A lipid is a macromolecule that contains hydrocarbon chains.
• What is the function of lipids?

  Energy storage, insulation, and protection of organs.
• What is the function of lipids?

  Lipids have many function such as storage of energy, providing structural support for cell membranes and act as signaling molecules.
• What are lipids made of?

  Lipids are made of carbon, hydrogen and oxygen.
• Are lipids hydrophobic?

  Lipids are hydrophobic and not water - soluble. However, there are some lipids that are amphipathic, such as phospholipids, which have hydrophilic part and a hydrophobic part.
• Are fatty acids lipids?

  Fats are one type of lipid, and therefore fatty acids are lipids.
• Are steroids lipids?

  Although steroids structurally look different, they are another class of lipids.
• Are lipids polar?

  Lipids are hydrophilic and therefore are considered non polar.
