  3. Effector
  4. Homeostasis
  5. Physiologic Subdivisions of Nervous System
  1. a * Deep glandular portion in the dermis innervated by sympathetic fibers
    * Coiled duct opens to skin surface via a pore
  2. b Sensory Input; Integrative; Motor Output/Response
  3. c Na⁺, Ca²⁺, Cl⁻, HCO₃
  4. d Metabolic equilibrium actively maintained by several complex biological mechanisms that operate via the autonomic nervous system to offset disrupting changes.
  5. e Organ or tissues that receive information (output) from the control center and produces a response.

5 Multiple choice questions

  1. When blood travels above adipose tissue, skin is {this}.
  2. Organ which is the body's thermostat by monitoring the temperature of the blood and signals it receives from the body's cold - hot receptors. It can respond to temperature changes as small as 0.01 °C. Regulates body core to 98.6 - 99.7 °F.
  3. Any stress that changes a controlled condition (set point).
  4. The maintenance of temperature involving several negative feedback loops controlled by a cluster of neurons called hypothalamic thermostat in the hypothalamus.
  5. Pyrogens increase hypothalamic thermostat set point suddenly initiating a cascade of events: dermal vasoconstriction, shivering, piloerection, hot sensation due to chemical thermogenesis.

5 True/False questions

  1. Internal Environment Factors Homeostatically MaintainedNutrient concentration; oxygen/carbon dioxide concentration; waste product concentration; pH; salt and ion concentration; temperature.


  2. Phospholipid BilayerLow permeability to water-soluble substances (e.g. ions, glucose, and amino acids), but permeable to lipid-soluble substances (e.g. fatty acids, oxygen, and carbon dioxide).


  3. Anatomic Subdivisions of Nervous SystemSystem comprised of eight ductless glands that secrete hormones directly into the blood to regulate the target organ function.


  4. Nervous TissueSkeletal, Smooth, Cardiac


  5. Shell TemperatureMost important physiological temperature. The temperature of deep tissues. Varies between 99 °F and 99.7 °F (101 °F in active children).
