Neuroanatomy

The study of anatomy and stereotyped organization of the nervous system

Neuro... Nervous... Nervous System

Axon Terminal

Where axons make contacts with other nerve cells

Terminal is where buses meet

Axon

Conducts electrical impulses away from neurons cell body

All or none principle

The principle that under given conditions the response of a nerve of muscle fiber to a stimulus at any strength above the threshold is the same.

The muscle or nerve responds completely or not at all

Medulla

Involuntary functions like regulating blood pressure and breathing


Helps transfers neural messages from the brain to spinal cord

Lower part of brain stem

Medulla

Involuntary functions like regulating blood pressure and breathing


Helps transfers neural messages from the brain to spinal cord

Lower part of brain stem

Pons

Message station between several areas of the brain


Helps relay messages from cortex and the cerebellum

Thalamus

Diagnoses sensory information that's being transferred from the brain including auditory, visual, tactile(touch) and gustatory(taste)

Hypothalamus

Reason why we know why we hungry or thirsty


Body temperature


Controls pituitary gland

Above pituitary gland and below thalamus

Corpus Callosum

Connects the left and right hemisphere of the brain

Amygdala

Responsible for response and memory of emotions especially fear

Amygdala

Responsible for response and memory of emotions especially fear

Hippocampus

Responsible for processing of long term memory and emotional responses

Antagonist

Chemical or drug that binds the receptors in the brain and prevents an agonist from having no reaction

Antagonist

Chemical or drug that binds the receptors in the brain and prevents an agonist from having no reaction

Neural Firing

Response of a neuron when it is stimulated

Antagonist

Chemical or drug that binds the receptors in the brain and prevents an agonist from having no reaction

Neural Firing

Response of a neuron when it is stimulated

Kinesthetic Sense

The sense of body position and movement of body parts relative to each other

Occipital Lobes

Visuals

Occipital Lobes

Visuals

Temporal Lobes

Sensory input and hearing

Occipital Lobes

Visuals

Temporal Lobes

Sensory input and hearing

Frontal Lobe

Personality

Parietal Lobe

Sensation and perception

Spinal cord

Connects large part of peripheral nervous system to the brain. Information(Nerve impulses) reaching the spinal cord through sensory neurons are transmitted up into the brain

Hormone

Substance produced by organism

Dopamine

Compound present as neurotransmitters and a precursor of other substances including epinephrine

Serotonin

Compound present in blood platelets and serum that constricts the blood vessels and act as a neurotransmitter

Serotonin

Compound present in blood platelets and serum that constricts the blood vessels and act as a neurotransmitter

Adrenal Glands

Cortex (outer portion) secretes steroid hormones


Medulla(inner) secretes epinephrine and norepinephrine
