Lecture 8 Flashcards
What makes up the nervous system?
central nervous system (CNS) and peripheral nervous system (PNS)
What makes up the CNS?
brain and spinal cord
What does the PNS do?
Connects the CNS to the rest of the body
Describe the processes and function of the autonomic nervous system.
Controls our internal organs & glands, is generally considered to be outside voluntary control.
What are subcortical structures?
A group of diverse neural formations deep within the brain (include the diencephalon, pituitary gland, limbic structures and basal ganglia). They are involved in complex activities such as memory, emotion, pleasure and hormone production.
What does the frontal lobe do?
The brain’s main motor centres located at front of head.
What is the limbic system?
Involved in processing emotion, learning & memory, smell projects here (can evoke emotional responses in ways that other sensory modalities cannot),
what makes up the limbic system?
made up of diff structures; hippocampus, amygdala, hypothalamus.
What does the occipital lobe do? what does it contain?
Located at very back of brain, contains the primary visual cortex (responsible for interpreting incoming visual info).
What does the temporal lobe do? Where is it located?
Located on the side of the head (hearing, memory, emotion, language).
What does the parietal lobe do? What does it include?
Includes the upper part of the spinal cord, the brain stem, and cerebellum. Controls respiration and heart rate.
Identify features & functions of the forebrain.
Contains the cerebral cortex & other structures that lie beneath the cortex (subcortical structures): thalamus, hypothalamus, pituitary gland & the limbic system.
What is the corpus callosum?
Thick band of neural fibres that connect hemispheres (200 million axons)
What does the corpus callosum do?
What are cortical structures?
Cortical areas are areas of the brain located in the cerebral cortex. The cerebral cortex refers to the superficial part of the brain and containing gray matter of the cerebral hemispheres.
Define Sulcus
little dips and grooves that increase our brains surface
What is the biggest Sulcus in our body
Longitudinal Suclus
how is our brain organized
contraleterally
do our left and right hemisphere function independently?
no
Define Corpus Callosum and its function
a handful of neurons that go from one hemisphere to the next
allows left and right hemisphere to communicate
Which side of the brain allows us to produce speech and understand speech
left
What are the 3 different areas of the brain
Hindbrain, Midbrain, Forebrain
What is the Hindbrain responsible for
automatic processes (ex; blinking, breathing, heart beat, balancing, walking, riding a bike)
What is the midbrain responsible for
making neurotransimitter
what is the forebrain responsible for
ability to think, listen, hope, feel, learn
Were is the cerebellum found
Hindbrain
Were do the singals for fine motor movement origanate
Forebrain
What is the cerebellum in control of
Fine Motor Movements (balance, walking, running, riding a bike)
Where are fine motor movements refined
cerebellum
where is the reticular formation located
how alert you are
Where is the medulla located
hindbrain
What is the medulla in charge of
automatic processes (heart beating, breathing, blood circulation)
Where are pons located
hindbrain
what do pons do
relays information from cerebellum to rest of brain
Were is Substina Nigra located
Mid brain
What does Substina Nigra do
makes dopamine
Where is ventral tegmental area located
Mid brain
what does ventral tegmental do
Produce dopamine
Where is Raphe Nuclei located
Mid brain
What does Raphe Nuclei do
makes serotonin
Where is Locus Coeruleus
Mid brain
What does Locus Coeruleus do
makes norapinephrine
what is the frontal lobe made up of
4 lobes and subcortical stuctures that are just underneath the cortex
What is the frontal lobe in charge of
Executive functioning (concentrating, thinking, sitting, making judgments)
