Compared with nervous coordination, endocrine coordination is:

  1. slower acting and longer lasting
  2. faster acting and shorter lasting
  3. faster acting and longer lasting
  4. slower acting and shorter lasting
Show answer and solution

Correct answer: A. slower acting and longer lasting

1. Nervous coordination sends electrical impulses along neurones, which travel in milliseconds. 2. Endocrine coordination sends hormones through the bloodstream, which takes seconds to minutes. 3. So the endocrine route is the slower of the two. 4. A nerve impulse stops as soon as stimulation stops, giving a brief effect. 5. A hormone persists in the blood until it is broken down, so its effect lasts far longer. _Source: NECTA ACSEE 2023 Biology 133/1, Question 7: Coordination_

The message in nervous coordination travels as:

  1. a hormone carried in the blood plasma
  2. a mineral ion diffusing through tissue
  3. an electrical impulse along a neurone
  4. a protein carried by a red blood cell
Show answer and solution

Correct answer: C. an electrical impulse along a neurone

1. The two systems differ in the nature of the message they send. 2. Nervous coordination transmits an electrical impulse along the membrane of a neurone. 3. At a synapse the impulse is briefly carried by a chemical transmitter, then becomes electrical again. 4. Endocrine coordination is the system that uses a chemical, the hormone, carried in blood plasma. 5. Red blood cells carry oxygen, not coordinating signals. _Source: NECTA ACSEE 2023 Biology 133/1, Question 7: Coordination_
