5 Matching questions

  1. Graded Potential
  2. Anterior Pituitary
  3. Epithelial Tissue
  4. Connective Tissue
  5. Resting Potential
  1. a In a neuron, a shift in the membrane potential that has an amplitude proportional to signal strength and that decays as it spreads.
  2. b The membrane potential characteristic of a nonconducting excitable cell, within the inside of the cell more negative than the outside
  3. c A portion of the pituitary that develops from nonneural tissue, consists of endocrine cells that synthesize and secrete several tropic and non tropic hormones
  4. d Sheets of tightly packed cells that line organs and body cavities as well as external surfaces
  5. e Animal tissue that functions mainly to bind and support other tissues, having a sparse population of cells scattered through an extracellular matrix

5 Multiple choice questions

  1. The ventral part of the vertebrate forebrain; functions in maintaining homeostasis, especially in coordinating the endocrine and nervous systems; secretes hormones of the posterior pituitary and releasing factors that regulate the anterior pituitary
  2. The junction where a neuron communicates with another neuron or other cell across a narrow gap via a neurotransmitter(chemical) or an electrical coupling.
  3. ...
  4. ...
  5. One of the three divisions of the autonomic nervous system; consists of networks of neurons in the digestive tract, pancreas, and gall bladder; normally regulated by the sympathetic and parasympathetic divisions of the autonomic nervous system. (secretions + peristalsis can function independently from parasympathetic and sympathetic but can also be affected by it)

5 True/False questions

  1. TissuesAn integrated group of cells with a common structure, function or both

          

  2. Parasympathetic DivisionOne of the three divisions of the autonomic nervous system, generally enhances body activities that gain and conserve energy, such as digestion and reduced heart-rate, decrease breathing, storing glycogen for energy in the liver

          

  3. MyofibrilsA longitudinal bundle in a muscle cell (fiber) that contains thin filaments of actin and regulatory proteins and thick filaments of myosin

          

  4. Sarcomere.Muscle in which the regular arrangement of filaments creates a pattern of light and dark bands

          

  5. Central Nervous System (CNS)The portion of the nervous system where signal integration occurs; in vertebrate animals, the brain and spinal cord
