Q

What is the human nervous system and what are the 3 main steps

A

Q

What is the CNS and what does it consist of

A

The CNS consists of the brain and the spinal cord

Its main function is to process information received from the body’s internal and external environments and to activate an appropriate response

Q

What is the spinal cord

A

The spinal cord is the long thin bundle of nerve tissue that extends from the base of the brain to the lower back (route for messages to and from the brain)

Q

What does the PNS do?

A

Carries information to the CNS from your body organs, muscles and glands (internal environment) and from the sensory organs (external Enviroment)
- Carries information from the CNS to the body muscles organs and glands
- The PNS does those via the teo sub divisions somatic nervous system and the autonomic nervous system

Q

What is the Autonomic nervous system

A

The autonomic nervous systen (ANS) is a subdividon of the PNS that connects the CNS to the body internal organs eg heart liver etc and also glands which provides feedback to the brain about there activities

Q

What are the divisions of the ANS

A

There are two divisions of the ANS which complement and counterbalance each others activities

1 - Sympathetic nervous system, which is responsible for increasing the activity of most muscles, organs and glands

2 - Parasympathetc NS, This NS is responsible for decreasing the activity of most muscles organs and glands

Q

What is the Reticular formation and what is it responsible for

A

A net like structure of neurons which extends along the brainstem, connecting various parts of the brain and spinal cord
- Filters. information to the brain
- Regulating the sleep/wake cycle
- Regulatings physiological arousal and alertness

Q

Define the Forebrain and the parts of it

A

The largest area of the brain located at the top and front of the brain
- Cerebrum: Responsible for range of sophisticated functions
-Thalamus: Filters info for motor and sensory signals
-Hypothalamus: Involved in homeostatic functions aswell as emotional behaviours

22
Q

What connects the 2 hemispheres of the brain and what is its function

A

The thick band of nerve fibres connecting the 2 hemispheres is called the corpus callosum, this allows for communication

23
Q

What is the cerebral cortex

A

The tissue that forms the outer layer of the upper part of the cerebrum
- It controls both basic sensory and motor skills as well as higher mental functions eg language memory etc

24
Q

What is the frontal lobe

A

Speaking
Planning
Judging
Abstract thinking
Personality aspects
Physical movement

25
What does the parietal lobe control
Sense of touch Body position
26
What does the occipital lobe do
Information Related to sight
27
Temporal lobe
Comprehension Sound Speech
28
What are neurotransmitters
The bodys natural chemical messages to be sent along the neuron, while other neurotransmitters can inhibit (slow or stop) activity
29
What is the synapse
The site where communication occurs between adjacent neurons COMPONENTS OF A SYNAPSE - Axons/terminal, buttons on the presynaptic (sending) neuron - Dendrites of the postsynaptic (receiving) neuron - Synaptic gap
30
Explain Neural Communication
Comminication occurs by sending a neurotrnsmitter across a synapse from yhr parasympathetic neuron to the postsynaptic neuron
31
Explain the process of neural communication
-When carrying a message to another neuron neurotransmitter binds to receptor sites of postsynaptic neurons -Postsynaptic neurons are specialised to receive that specific neurotransmitter
32
Types of Neurotransmitters: Adrenaline
Produced in stressful or exiting situations. Increases heartrate & blood flow, leading to a physical boost & higher awareness
33
Types of Neurotransmitters: Noradrenaline
Affects attention & responding actionin the brain and is involved in fight/flight response, contracts blood vessels , increases blood flow
34
Types of Neurotransmitters: Dopamine
Feelings of pleasure and also addiction, movement and motivation. People repeat behaviours that lead to dopamine release
35
Types of Neurotransmitters: Serotonin
Contributes to well being & happiness, helps sleep cycle aswell as the digestive system. This is affected by exercise and light exposure
36
Types of Neurotransmitters: GABA
Calms firing nerves in CNS. High levels imporves focus; low levels cause anxiety. Also contributes to motor control & vision
37
Types of Neurotransmitters: Acetylcholine
Involved in thought, learning and memory. Activates muscle action in the body. Also associated with attention and awakening
38
Types of Neurotransmitters: Glutamate
Most common brain neurotransmitter involed in learning & memory, regulates development & creation of nerve contracts
39
Types of Neurotransmitters: Endorphins
Released during exercise, exitement & sex, producing well being and euphoria, reducing pain. Biologically active section shown
40
Explain conscious response
An action coordinated by the body that is performed with voluntary control and intention - Awareness of the brain
41
Explain Unconscious response
An action coordinated by the body that occurs automatically - Without awareness of the brain
42
- Reaction involves the brain and a level of awareness - Paid attention to stimuli - Voluntary or intentional reaction - Often goal-directed or purposeful - Can be a more complex response - Tend to Vary - Can be learned - Can control it This is ________
Conscious response to stimuli
43
- Reaction does not involve a level of awareness by the brain - Do not have to pay attention for it to happen - Involuntary or unintentional - Reflexive or automatic, increasing chances of survival - Most are simple responses - Tend to occur in the same way each time - Do not require learning - May not be able to control it This is ______ response to stimuli
Unconscious response to stimuli
44
What is the spinal reflex
A spinal reflex is an unconscious, involuntary and automatically occurring response to certain stimuli without any involvement of the brain.
45
What are conscious experiences
Thought - Mental conditons: our ideas, opinions and beliefs about ourselves and the world around us Feeling - An emotional state Behaviour - Observable actions These three are interconnected and interdependent
46
What are the Spinal cord nerves
Cervical -Head and neck -Diaphram -Deltoids and bicep -Wrist extendors -Triceps -Hand Thoracic -Chest muscles -Abdominal muscles Lumbar -Leg muscles Saceral -Bowel and bladder Sexual frustration
47
Describe spinal cord injury
The level where the injury occurs determins the effects that the person suffers Spinal cord damage is classified according to the persons type of loss of motor and sensory function.
48
Explain the types of spinal cord injury
Quadriplegia: Four limbs affected by impaired sensation and movement. If spinal injury is high up the spine, then chest muscles like diaphragm can be affected. Paraplegia: Two limbs affected (Left&right legs) by impaired sensation and movement. Triplegia: Rare incomplete spinal cord injury leads to 3 limbs (1 arm 2 legs) affected byimpaired sensation and movement
49
Symptoms of spinal cord injury
- Muscle weakness or paralysis -Sensory dysfuction such as loss of sensation or pins and needles - Sexial dysfunction -Digestive problems
50
What is Clinical Psychology
psychology that deals with the prevention, assessment, diagnosis and treatment of psychological problems and mental disorders.
51
Explain Mentally Healthy
- Being in a positive state of mind - Coping with life's daily challenges - Working productively - Being able to connect with others
52
Explain mental health problem
- Affects the way a person thinks, feels and behaves - Normal, short-term reaction to daily challenges
53
Mental health disorder
- a State where you act, feel and think negatively usually by personal distress - Difference between a mental health problem is = Lasts longer =Causes disruption to a person's life
54
