Neurospchology

The Nervous system is divided into: The [blank_start]central nervous system[blank_end] is made up of [blank_start]your brain and spinal cord[blank_end]. It [blank_start]transmits messages[blank_end] to the [blank_start]peripheral nervous system[blank_end].

The Brain is involved in:

The spinal cord is involved in:

The [blank_start]somatic[blank_end] nervous system ([blank_start]voluntary[blank_end] movement) is concerned with the [blank_start]external environment[blank_end] and carries information to ([blank_start]sensory[blank_end] neurons) and from ([blank_start]motor[blank_end] neurons) the [blank_start]central[blank_end] nervous system.

The [blank_start]autonomic[blank_end] nervous system ([blank_start]involuntary[blank_end] movement, controlled by the [blank_start]central[blank_end] nervous system [blank_start]unconsciously[blank_end]) is concerned with the [blank_start]internal[blank_end] environment. It connects info from the [blank_start]central[blank_end] nervous system to the [blank_start]internal organs[blank_end], [blank_start]glands[blank_end] and [blank_start]smooth muscles[blank_end] (eg, digestion), [blank_start]regulating internal bodily processes.[blank_end]

Can the Somatic Nervous system be split into further branches?

The [blank_start]sympathetic[blank_end] branch prepares the body to [blank_start]expend energy[blank_end] (mobilising the body for an emergency-fight or flight response). The [blank_start]parasympathetic[blank_end] branch [blank_start]conserves[blank_end] energy and caries out 'maintenance needs' such as [blank_start]tissue repair[blank_end]. Parasympathetic activity occurs when we are [blank_start]relaxed or inactive[blank_end] (most of the time) or when the [blank_start]stressor/emergency has passed.[blank_end]

The parasympathetic branch:

The Sympathetic branch:

When we are faced with a stressor we don't think that we can deal with, the [blank_start]hypothalamus[blank_end] sends a message to the [blank_start]sympathetic[blank_end] branch which sends a message to the [blank_start]adrenal medulla[blank_end] which then [blank_start]releases adrenaline[blank_end], which has effects such as increased [blank_start]heart rate[blank_end], [blank_start]blood pressure[blank_end] and [blank_start]breathing rate[blank_end] and decreased [blank_start]digestion[blank_end] which is not a priority, preparing your body for the [blank_start]fight/flight response.[blank_end]

When the threat passes, the sympathetic branch is activated.

Who came up with the fight/flight response theory?
