Human Nervous System Flowchart(CNS, PNS

Human Nervous System Flowchart(CNS, PNS

Human Nervous System -> CNS and PNS, CNS -> Brain and Spinal Cord

PNS -> Somatic and Autonomic, Autonomic -> Parasympathetic Nervous System,

Sympathetic Nervous System, Enteric Nervous System

Differentiate between the role of the Sympathetic Nervous system(fight-flight) and the Parasympathetic Nervous system(Rest and digest, homeostatis) and Enteric nervous system subdivisions of the autonomic nervous system

Parasympathetic – relaxes body after stress or danger

Sympathetic – response to stress or danger

Enteric – the system of nerves connecting the gut and digestive tract to the brain.

Be able to draw a motor neuron and label it

Know the structure and function of the neuron

Don’t be a bitch

Describe neural transmission referencing lock and key theory

The neural transmission is the transmission

of electrochemical messages which travel throughout the different nervous systems. The lock and key theory describes the

neurotransmitters as the key to the lock which are the receptors on the post synaptic neuron.

Draw and annotate the synapse

What is the role of glutamate

Glutamate is an excitatory neurotransmitter which increases the likelihood of the

post synaptic neuron (dendrite) firing

What is GABA

GABA is an inhibitory neurotransmitter which decreases the likelihood of the

post-synaptic neuron (dendrite) firing.

What are neuromodulators

Other neuromodulators have excitatory or inhibitory effects at the synapse

and cause different effects in the brain.

What is serotonin

Serotonin is important in mood regulation; low levels lead to depression.

What is dopamine

Dopamine is reward based (low levels lead to ADHD and Parkinson’s disease)

and causes structural changes in neural connections at the synapse,

linked heavily to addiction.

What’s Acetycholine

Acetylcholine activates the nervous system and plays an important role in attention,

memory, and learning (low levels are seen in Alzheimer’s disease).

Causes, effects and symptoms of Multiple Sclerosis as a neurological disease(MS)

Multiple Sclerosis is a neurological disease which eats away at the myelin

sheath on neurons, there is no known cause for MS, but people suffer from

it because of the damage to the myelin sheath, and symptoms include slower reactivity

What is Neuroplasticity

Neuroplasticity is the brain and neuron’s ability to change and adapt due to learning,

experiences, trauma, and development.

What are the two types of neuroplasticity and what do they entail

There are two types of plasticity, developmental and adaptive, developmental plasticity

refers to the changes in neural connections during development, while adaptive plasticity

includes the ability to learn new information and skills.

What is the structure and function of the cerebral cortex

Cerebral Cortex includes lots of folds in the brain, allowing for more surface area

and therefore, more neurons. There are two hemispheres, the left and right

(Left hemisphere controls rights side of body, right hemisphere controls left side of body).

Label all four lobes and regions of the cerebral cortex

There are four lobes in the brain, Frontal Lobe, Temporal Lobe, Occipital Lobe,

and Parietal Lobe. There are also other areas in the brain such as the cerebellum

and brain stem.

What is the location and role of the corpus callosum

The corpus callosum is in the middle of the brain, in between the two

hemispheres and connects the two hemispheres together, maintaining

connection and communication between each side.

List 3 functions of the right hemisphere

Creativity, imagination, and curiosity.

List 3 functions of the left hemisphere

Rules, Strategy, and Logic.

Stile Component 1

Role of nerves in the PNS is to carry information to and from the spinal cord.

The main way the CNS controls actions is through sending messages to

activate muscles.

Communication in the nervous system is electrochemical because an

electric charge is used when information is being transferred between

neurons, but when its inside a neuron, the impulse is chemical in nature.

Stile Component 2

The man with the 7-second memory is unable to retain his

short-term memory, involved with the hippocampus.

Amnesia, the hippocampus, and amygdala, unable to

create new long-term memories.

Short term memory film study, the prefrontal cortex.

Occipital Lobe responds to visual lines, and orientation.

Oversees visual perception, colour, and motion.

Stile Component 3

Mice with more Chemical X gut microbes are more anxious.

We can use the gut-brain connection to prove gut feelings

which can help with decision making.
