Biopsychology Flashcards
What is the function of the endocrine system
Releases hormones into the bloodstream to regulate moods and emotions along with regulating physical needs such as reproduction, growth and development etc.
What is the difference between the endocrine system and TNS
The main difference is that while the nervous system transmits information
via nerves, the endocrine system uses blood vessels to deliver hormones to
their target sites in the body.
What are hormones
Hormones are chemicals that circulate in the bloodstream and are carried to target sites throughout the body.
What 2 parts are our Nervous System split into
Central Nervous System
Peripheral Nervous System
What 2 major things does the CNS control
Brain
Spinal Chord
What is the role of the Nervous System
Relay messages from the brain to the rest of the body to instruct what to do
What is the Peripheral Nervous System further broken down into
Somatic NS
Autonomic System
What is the Autonomic System further broken into
Sympathetic system
Parasympthathetic System
What is the function of the brain
The brain majorly focuses on processing mental thoughts
Has overall ‘control’ over the rest body functions
What is the Spinal Cord responsible for
Passing messages from the brain to the rest of the body (form of electrical impulses)
Transmitting messages back to the brain from various parts of the body
What is the purpose of the somatic nervous system
Concious
Passing messages from sensory organs to the brain
Controls the body’s conscious actions (voluntary)
- Movement etc.
What is the purpose of the autonomic NS
Controls the body’s automatic actions such as breathing
The functions happen quickly so we do not think about it
No conscious thought over the decision
What is the role of the Sympathetic NS
Body’s Alert System
Prepared to respond to threats (fight or flight)
What is the role of the Parasympathetic System
Relaxes the body by counteracting the SNS activation
Cools the body rather than elevate it to prepare for threats
What physical factors takes place during the activation of the Sympathetic Nervous System
Increased heart rate
Pupils Expand
Reduced activity in stomach
Sweat Excess
