The Structure Of Function Of The Nervous System Flashcards
Any Changes (Known As Stimuli) are Picked Up by Cells Called _____________.
Receptors.
Receptor Cells are Similar to Most ____________ Cells. They have a Nucleus, _____________ and a Cell Membrane.
Animal…Cytoplasm…
Receptors are Usually Found Clustered Together in Special _________ Organs.
Sense.
Once a Sensory Receptor Detects a _____________, the Information is Sent as an Electrical Impulse that Passes Along Special Cells Called ______________.
Stimulus…Neurones…
Neurones are Found in Bundles of Hundreds or Even Thousands Known as __________.
Nerves.
An Electrical Impulse Travels Along the Neurone until it Reaches the Central Nervous System (______).
CNS.
What is the CNS Made Up of?
Brain and Spinal Cord.
Cells that Carry Impulses From your Sense Organs to your CNS are Called ____________ Neurones.
Sensory.
Motor Neurones Carry Information From the CNS to the Rest of the _______. They Carry Impulses to make ____________ Respond.
Body…Effectors…
What May Effectors be?
Muscles or Glands.
How do Muscles Respond to the Arrival of Impulses?
By Contracting.
How do Glands Respond to the Arrival of Impulses?
By Releasing (Secreting) Chemical Substances.
How Nervous System Works (Summed Up)?
Stimulus –> Receptor –> Coordinator (CNS) –> Effector.
