Nervous System And Endocrine Systems Flashcards
1
Q
Homeostatis
A
Balance - Body’s ability to keep phsilogical functions within normal limits.
Ex. Body Temp = Shivering when cold / Sweating when hot
Water Water - Dehyrdated = drink more water / Pee out water
2
Q
Nervous System
A
- Ensure homeostasis
Rapid nerve impulses, Fast/Quick/Rapid/Short
3
Q
Endocrine System
A
Glands release horomones into bloodstream
- Slow, more long-lasting
4
Q
Central Nervous System (CNS)
A
2 Parts
- Brain
- Spinal Cord
5
Q
Peripheral Nervous System (PNS)
A
- Everything else
- Carries info between organs of body and the CNS
- Divided into 2 (SN, AN)
6
Q
Somatic Nerves
A
- Voluntary
- Myelinated Nuerons
- Fast nerve transmisson
Brain tells to do something with choice
Ex, Raise Arms
7
Q
Autonomic Nerves
A
Involuntary
- Automatic
- Slower nerve transmisson
- Unmyelinated Neurons
- Dont have to think about it
- Sympathetic, Parasympathetic
8
Q
Parasympathetic
A
- Rest and Digest
- Nerves transmit impulses returning to normal after time of
stress - Slows functions (Heart rate / Blood pressure)
- Nerves originate in the brain
9
Q
Sympathetic
A
- Fight or Flight
- Nerves transmit impulses during
times of stress - Speeds up functions (Heart rate / Blood pressure)
- Nerves originate in the spinal cord
