Question | Answer |
---|---|
Astrocyte | These cells connect neurons together and to their blood supply. They establish the blood-brain barrier |
Central Nervous system (CNS) | Brain and spinal cord - The group of nerves that run through the center of the spine, caries messages between the brain and the rest of the body |
Peripheral Nervous system (PNS) | The nervous system that lying outside of the brain and the spine |
Somatic Nervous system (SNS) | Controls voluntary movements in the body |
Autonomic Nervous system (ANS) | Regulates key involuntary functions of the body. Innervates the blood vessels, heart, smooth muscles |
______and ______are two types of nervous system cells | Neurons and neuroglia |
perform phagocytosis, engulfing microorganisms and cellular debris | Microglia |
Cells that regenerate | basal cells |
Production of Insulin is located in the ___________ | Pancreas |
Parathyroid gland | regulates calcium and phosphate balance |
The __________is part of the SNS and produces epinephrine | adrenal medulla |
Primary organ of the lymphatic system | Thymus |
Erythrocyte | Red Blood Cell Transports respiratory gasses O2 & CO2 Life Span 105 - 120 Days |
Neutrophils | White Blood Cell Cellular Defense - phagocytosis of small pathogenic microorganism Life Span - hours to 3 days |
Basophil | White Blood Cell Secretes heparin (anticoagulant) and histamine Life Span - hours to 3 days |
Eosinophil | White Blood Cell Cellular Defense - some phagocytosis; chemical attack of large pathogenic microorganisms (such as protozoa) and parasitic worms; helps regulate allergic reactions and other inflammatory responses Life Span - 10 to 12 days |
Lymphocyte | White Blood Cell Humoral defense - secretes antibodies; involved in immune system response and regulation Life Span - days to years |
Monocyte | White Blood Cell Capable of migrating out of the blood to enter tissue spaces as a macrophage - an aggressive phagocytic cell capable of ingesting bacteria, cellular debris, and cancerous cells Life Span - months |
Platelets | Releases clot-activating substances and helps in formation of actual blood clot by forming platelet plugs Life Span - 7 to 10 days |
