Unit 2 ap pysch

Partietal Lobe

receives and associates sensory input from the body

dendrite

receives incoming messages

somatic nervous system

responsible for voluntary muscle control.

afferent

sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain

Nervous system sends

signals and responses instantly via electricity(text messages)

Parathyroid

located behind the thyroid gland.Regulates blood calcium levels

efferent

motor neurons that carry neural impulses away from the central nervous system and towards muscles to cause movement

motor(efferent) neurons

neurons that carry outgoing information from the brain and spinal cord to the muscles and glands

Inter neurons

neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs

Spinal cord

Central transmission line for sensory input and all autonomic and somatic neuron communication.

Thyroid

Located in the nec, controls hormones that boost or reduce metabolism

Sensory(afferent) neurons

Neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain.

autonomic nervous system

Oversees involuntary functions of the body

Neurotransmitters

chemical messengers that cross the synaptic gaps between neurons

Reuptake

"Clean up"-excess transmitters are reabsorbed for use later.

resting potential

"at ease"- no signal, more positive ions outside than inside the axon.

Permability

"charging my laser", getting ready to fire-ions are getting closer and more excited as potential rises.

action potential

"fire"-neutral threshold has been met and the neuron sends the signal down the entire axon in a sweep.

Cerebullum

"little brain" responsible voluntary motor balance and coordination.

Refractory period

"on a break"- no signal can be sent, neuron is resting/gaining potential.

Phineas Gage

railroad worker who survived a severe brain injury that dramatically changed his personality and behavior; case played a role in the development of the understanding of the localization of brain function

Parasympathic

A polygraph machine is often called a lie detector although it does not detect lies instead it responds to( measure changes in heart rate and blood pressure and skin conductivity via sweat) to determine whether someone is lying or not.

Adrenal glands

Above kidney, release adrenaline in fight or flight situations.

Hypothalamus

Above the pituitary gland attached to the brainstem.serves as the bridge between nervous and Endocrine system.controls body temperature.

A decrease heart rate

Activation of the parasympathetic nervous system results in which of the following?

pituitary gland

Also called master gland.plays in essential role y regulating and controlling the other endocrine glands.it affects vital parts like your brain, skin,mood,energy,reproductive organs, vision and growth.it tells other glands to release hormones.

The endocrine system

Comprised of 8 organs the coordinate the release of chemical messengers into the blood called hormones.

peripheral nervous system

Connecting all nerves and a structure that contains a number of nerve cell bodies outside the brain and spinal cord.

motor cortex

Controls all voluntary movement of the body.

Frontal Lobe

Controls impulses, future planning, judgement, logical thinking, and personality.

temporal lobe

Controls language comprehension and all auditory input.(smell,hearing,auditory association area)

Nucleus

Decides to fire the message or not

limbic system "old brain"

Emotion, motivation and memory are route through here.

sympathetic 1

Joel's pupils become dilated, his digestion is reduced, and his skin becomes cold.

Medulla

Part of the brainstem, responsible for involuntary functions such as heartbeat, sneezing, and vomiting.

Pineal gland

Produces and releases melatonin, which is responsible for regulating our sleep patterns.

endocrine system 1

Responses slowly through the blood stream(postal mail)

gonads

The primary reproductive organs, are testes in the male and the ovaries in a female.These organs are responsible for producing the sperm and ova.

Wernicke's area

a brain area involved in language comprehension and expression; usually in the left temporal lobe

association areas

areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking.linking it with stored memories.

Pancreas

below the lungs insulin and glucagon-to regulate appetite and hunger response.

Parasympathic response

calms you down and lowers your blood sugars.

transmitter

chemical messenger that carries information between nerves and body organs, such as muscles and heart

central nervous system

contains the brain and spinal cord

Broca's area

controls language expression - an area, usually in the left frontal lobe, that directs the muscle movements involved in speech.

Sensory cortex

controls pain perception and all skin senses(5 senses)

Sympathic responses

fight or flight response

Prosopagnosia

inability to recognize faces

Testosterone and adrenaline

takes longer for hormones to arrive but it can take them longer to leave, resulting in lingering feelings or moods

Endocrine system 2

this affect different tissues including the development of the brain and body, impacting our maturity, moods, feelings and behavior.

Increased digestion

which of the following is a parasympathetic nervous system response?
