Hypothalamus
________- regulates hunger, thirst, sleep and wakefulness.
Pituitary
________ glands- controls all other endocrine glands: influences growth, metabolism and regeneration.
Adrenal
________ glands- secrets adrenaline to prepare body for fight or flight response to help react to emergencies.
Ovaries
________ /testes- influences how your blood circulates and determines your mental vigor and sex drive.
Thymus
________- builds resistance to disease.
Synaptic transmission
________- action potential reaches the end of the presynaptic neuron and triggers the release of neurotransmitters from the vesicles.
spinal cord
The ________ is an extension of the brain and is responsible for reflex actions such as pulling away your hand from something hot.
Excitation
________- when a neurotransmitter such as adrenaline, increases the positive charge of the post synaptic neuron.
Inhibition
________- when a neurotransmitter such as serotonin, increases the negative charge of the post synaptic neuron.
Glands
________- an organ in the body that synthesises substances such as hormones.
Endocrine system
________- bodies major information systems that instructs glands to release hormones and carried towards target organs.
Sympathetic nervous system
________- Returns the body to its normal resting state.
synapse
The neurotransmitters diffuse across the ________ and bind to the receptors on the postsynaptic neuron.
Effects of hormone
________ produced- prepares body for fight or flight response.
brain
The ________ is the centre of all conscious awareness.
Neurotransmitters
________ are removed from the synapse by being broken down by enzymes.
nervous system
The ________- a specialised network of cells in the human body and is our primary internal communication system.
Parasympathetic nervous system
________- Involved inn preparing the body for a fight or flight response.
Excitatory neurotransmitters
________ make it more likely that the postsynaptic neuron will generate an action potential.
Thyroid gland
________- regulates energy and metabolism.
Effects of hormone
________ produced- increases positive emotions such as love.
The nervous system
a specialised network of cells in the human body and is our primary internal communication system
The two main functions of the Nervous System
To collect, process and respond to information in the environment
Central nervous system
made up from the brain and the spinal cord
Peripheral nervous system (PNS)
transmits messages via million s of neurons to and from the CNS
Autonomic nervous system
governs vital functions in the body such as breathing, heart rate, digestion, sexual arousal etc
Somatic Nervous System
controls muscle movement and receives information from sensory receptors
Parasympathetic nervous system
Involved inn preparing the body for a fight or flight response
Sympathetic nervous system
Returns the body to its normal resting state
Difference between somatic nervous system and the autonomic nervous system
the Somatic nervous system has sensory and motor pathways whereas the Autonomic Nervous System is purely motor
Sensory neurones
transmits sensory information from receptors via the spinal cord to the brain
Relay neurons
transmits information between neurons to allow for communication between different parts of the central nervous system
Motor neurons
transmits information to muscles and glands from the central nervous system
Synaptic transmission
action potential reaches the end of the presynaptic neuron and triggers the release of neurotransmitters from the vesicles
Excitation
when a neurotransmitter such as adrenaline, increases the positive charge of the post synaptic neuron
Inhibition
when a neurotransmitter such as serotonin, increases the negative charge of the post synaptic neuron
Distinguish between sensory and relay neurons
sensory neurons transmit sensory information from the receptors via the spinal cord, to the brain where as a relay neuron transmits information between neurons to allow communication between different parts of the central nervous system
Hypothalamus
regulates hunger, thirst, sleep and wakefulness
Thyroid gland
regulates energy and metabolism
Thymus
builds resistance to disease
Adrenal glands
secrets adrenaline to prepare body for fight or flight response to help react to emergencies
Ovaries / testes
influences how your blood circulates and determines your mental vigor and sex drive
Endocrine system
bodies major information systems that instructs glands to release hormones and carried towards target organs
Glands
an organ in the body that synthesises substances such as hormones
Example of a gland
hypothalamus
Hormone produced
oxytocin
Effects of hormone produced
increases positive emotions such as love
Example of gland
adrenal gland
Hormone produced
adrenaline
Effects of hormone produced
prepares body for fight or flight response
