Week 7-13 Content
| Question | Answer |
|---|---|
| What is the name of the cell that conducts impulses/transmits information | Neuron |
| What Part of the Neuron contains the Nucleus | cell body |
| Where are the brain and spinal cord is located? | The central nervous system. |
| what are the two different types of nervous cells? | Neuron and Neuroglia |
| Where do the impulses from the facial and glossopharyngeal nerves travel to finally make it to the gustatory cortex? | Solitary nucleus in medulla oblongata, through the pons, through the thalamic nucleus, and then into to gustatory cortex. |
| Endocrine system general functions | Act with nervous system to coordinate and integrate activity of body cells, Influences metabolic activities via hormones. |
| Hypothalamic release of hormones from the pituitary gland | Produces oxytocin and antidiuretic hormone (ADH) |
| What's the job of Posterior lobe of pituitary gland | Receives hormones from the hypothalamus and releases them ex. ADH and oxytocin |
| Blood Vessels that bring blood back to the heart | 1. Superior Vena Cava 2. Inferior Vena Cava 3. Coronary Sinus |
| First two branches off of the Aorta | 1. LCA (Left Coronary Artery) 2. RCA (Right Coronary Artery) *These feed the heart; 'Blocked Artery' usually happens here |
| venous blood from the heart enters | The right atrium from the coronary sinus |
| What are the three parts of the lymphatic system? | lymph vessels/ lymphatics lymph lymph nodes |
| What are the functions of our lymphatic system? | - Transports lymph and "junk" from the tissues back to the cardiovascular system. - Filters the lymph fluid in lymph nodes to destroy pathogens as part of the immune system. - Nourishes cells in the lymphatic system. |
| What is the role of antimicrobial proteins (interferons and complement?) | - A cells that has a virus in it is dead. - Viral-infected cells are activated to secrete interferons (IFNs.) IFNs enter neighboring cells causing them to produce antiviral proteins that block viral reproduction |
| What is an antigen? | - Cells have proteins, polysaccharides, glycoproteins, and glycolipids on their surfaces. - These molecules act as antigens when they cause an immune response. - The body learns to recognize its own antigens as "self." MHC are "self" proteins. |
| Active cells of B lymphocytes | Effector Cells Memory cells |
| Adaptive Immunity | Uses lymphocytes, APCs, and specific molecules to identify and destroy nonself substances |
| What is the primary organ of the respiratory system? | The lungs |
| How long can the body go without oxygen, before brain cells begin to die? | Four minutes |
| The tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream are called | Alveoli |
| What keeps the lungs from collapsing? | Differences in lung and pleural space pressures |
| How is oxygen carried through the blood? | Most oxygen travels attached to hemoglobin and forms oxyhemoglobin (HbO2). A small dissolved amount is carried in the plasma |
| What would happen to your respiratory rate if your blood pH became alkaline? | Results when blood becomes alkaline (alkalosis). Extremely slow or shallow breathing. Allows CO2 to accumulate in the blood |
