What makes up the CNS?
Spinal Cord and Brain
1 of 24
What makes up the PNS?
Somatic (skeletal) Autonomic (Sympathetic - fight or flight - increase heart rate, Parasympathetic - Rest and Digest lowers heart rate
2 of 24
What comprimises a reflex arc and why is it so fast?
Sensory neurone and motor neurone, because it only needs to reach the spinal cord, does not go to brain
3 of 24
Lobes of the Brain?
Frontal, Temporal, Pariental, Occupital
4 of 24
Regions of the brain and thier functions?
Cerebrum - Pesonality, emotions, problem solving and reason. Cerebellum - Co-ordination and balance Medulla - Regulates basic body functions
5 of 24
Low blood sugar levels
Pancreas produces glucagon which increases blood sugar levels
6 of 24
High blood sugar levels
Pancreas produces insulin which converts glucose into glycogen which is then stored in the liver.
7 of 24
What is Homeostasis?
Maintaining a constant internal environment - water, blood sugar and temp.
8 of 24
General name for organisms that cause disease?
Pathogens
9 of 24
What are viruses?
Microbes
10 of 24
Do viruses contain a cell?
They are non-cellular.
11 of 24
True or false. Viruses require a host cell to reproduce.
True
12 of 24
What hormones control sugar levels?
Insulin - Lower Glucagon - Raises
13 of 24
List the first line of defense.
Skin, Mucus, Tears, Saliva, Stomach acid.
14 of 24
The fight or flight response is in what part of the autonomic nervous system?
Sympathetic
15 of 24
How do hormones reduce body temp?
The pituitary gland stops secreting the thyroid-stimulating hormone which stops the thyroid from producing thyroxin when slows the motabolism (generates heat)
16 of 24
What gland produces the antidiuretic hormone?
Pituitary gland
17 of 24
What parts make up the nervous system?
Central Nervous System + Peripheral Nervous System (Somatic and Autonomic ( Sympathetic + Parasympathetic)
18 of 24
Name the main parts of the brain and thier functions.
Cerebrum - motor, personality, emotions, problem solving, reasoning Cerebellum - controls balance and coordination Medulla (brain stem) - Regulates basic body functions
19 of 24
What is a reflex action?
A reflex action is a fast, automatic response to a stimulus.
20 of 24
What system controls reflex actions?
The peripheral nervous system.
21 of 24
What does the somatic system control?
Sensory organs.
22 of 24
What does the autonomic system control?
Involuntary actions.
23 of 24
What function does the parasympathetic system have?
Rest and digest.
