Chapter 3 Biological Bases Of Behaviour Flashcards
The major system, the endocrine system, what are its major functions? name the key points
Uses the bloodstream to send and receive information •only chemical •slow •imprecise •long lived duration
What is the main function of the nervous system? Name the key points
Sending and receiving information. Electrical and chemical, fast, short duration, precise
What are the stages of the nervous system?
Input (eternal factor), processing (decision making), output (acting on decision)
What parts of the body are connected with the central nervous system (CNS)?
The brain and the spinal chord
What is the Peripheral nervous system (PNS) responsible for?
- somatic (muscles you control)
* autonomic (internal organs, blood vessels). (Can’t control)
Which type of autonomic organs spend energy and increase activation of the nervous system?
The sympathetic
Which type of autonomic organ calm the nerves and preserve energy?
Parasympathetic
Name the two type of of neurons
Sensory, motor
What is the purpose of the Gial?
Communication between neurons, direct neurons growth, maintain chemical environment, provides energy, clears metabolic waste
What is the Neuron good for?
Brain structures, communication between neurons
What part of the Neuron receives input from other neurons and generates messages?
Dendrite
What maintains the neurons health?
Cell body
What decides whether to send an action potential?
Axon Hilock
Fatty material that covers the axon. Active potential to flow smoothly.
Myelin Sheath
Nodes of ravier?
Small gaps
