What are the main components of the Central Nervous System? (CNS)
The Brain and the Spinal cord are full of neurons that allow quick reflexes. The spinal cord houses relay neurons to enable simple reactions without the brain's involvement.
1 of 9
Name and describe the two branches off of the Peripheral Nervous System .
The Autonomic Nervous system controls involuntary body functions like blood pressure, heart rate, and breathing. The Somatic Nervous System controls voluntary muscles and transmits sensory information to the CNS
2 of 9
Briefly describe the main functions of the Sympathetic Nervous System and the Parasympathetic Nervous System.
The Sympathetic nervous system is triggered during the flight or fight response. It prepares the body for an emergency. The Parasympathetic System works to counteract the SNS and calms the body
3 of 9
Name 5 main parts of a neuron
Dendrites, Axon, Myelin Sheath, Axon Terminal, Nucleus
4 of 9
Name the two types of neurotransmitters with examples
Excitatory- which increase the likelihood of the post synaptic neurons firing an impulse. E.g Dopamine. Inhibitory neurotransmitters decrease the likelihood of a neutron firing. E.g Serotonin
5 of 9
what does the Sympathetic Nervous system do to the body in the fight or flight response?
Diverts blood away from stomach and digestion to skeletal muscles and more important priorities at that moment. Increase heart rate na blood pressure. Increases breathing and dilates pupils.
6 of 9
What is the main function of the Parasympathetic nervous system
Restarts digestion, reduces Adrenal activity , reverts actions of the SNS.
7 of 9
What is the scientific name of the gland commonly referred to as the "master gland"
The Pituitary Gland
8 of 9
There are two parts of the Adrenal Gland, the Adrenal medulla and the Adrenal Cortex, what functions do these have?
The Adrenal Medulla produces Adrenaline used in the flight or fight response. The Adrenal cortex produces Cortisol that is also used in the flight or fight response and high levels are also linked to long term stressors.
