Chapter Three Flashcards
Neural Networks are organized groups so neurons that help you …
See, process and understand. Input, processing, output.
Sensory neurons access the …
Sensory receptors and access the central nervous system
Afferent Neurons, also called sensory neurons, are…?
Afferent neurons, also called sensory neurons, are the nerve fibers responsible for bringing sensory information from the outside world into the brain. Sensory information may involve special senses, such as vision, hearing, smell, or taste, as well as the sense of touch, pain, and temperature.
Writing something down is an example of ….
Motor production.
Interneurons function how?
Interneurons. As the name suggests, interneurons are the ones in between - they connect spinal motor and sensory neurons. As well as transferring signals between sensory and motor neurons, interneurons can also communicate with each other, forming circuits of various complexity.
Neurological is the branch of medicine that studies what?
(Hint: Neuro)
the branch of medicine that deals with problems affecting the nervous system. The word neuro means nerve and nervous system.
The brain has amazing Neuroplasticity; what does that mean?
is defined as the ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections after injuries, such as a stroke or traumatic brain injury (TBI)
The nervous system has two parts. What are they? (Hint: C.P)
Central nervous system
Peripheral nervous system
The central nervous system mostly consists of the brain and …
Brain and spinal cord
Peripheral system is responsible for the
Sensory and motor systems connection to the central nervous system.
What are the 4 parts of the peripheral nervous system?
- Somatic
- Autonomic
- Sympathetic
- Parasympathetic
The somatic nervous system functions by absorbing
Sensory information to the central nervous system and movement instructions to the muscles (voluntary movement.) eat now.
What does the autonomic nervous system control?
Involuntary movement-
No, no I’m over and eat your food for example, heart rate, blood pressure, breathing.
The sympathic system controls an important syndrome. What is it?
The fight or flight syndrome
The Perry sympathic system helps you recover from fight or flight syndrome, how?
It’s purpose is to conserve energy. Thus after you experience fight or flight, it helps calm you down.
Your medulla is often referred to as your “kill spot.” Why?
Because the medulla is responsible for your vital functions, breathing, and daily functioning, such as respiration, blood flow.
The reticular formation isn’t fully developed until you are an adolescent This is why some children have a hard time paying attention. Therefore, the reticular formation must be responsible for what?
Attention
What part of the brain is responsible for speech? 
Broca’s area
Temporal Lobe
Auditory information. You listen and then the information is sent to wernick’s area
Wernicks area is where we…
(Hint: wer… word.)
Process and understand the speech we hear
Occipital Lobe is where you take in
Visual information
Once visional information is taken in, it is brought to the ___ ____ ____
Primary Visual Cortex
Facial Agnosia is a condition where a person cannot …
{hint: Facial!}
Recognize faces
Perception could be simply defined as …
The ability to identify what you are seeing and then understanding it.
Left hemisphere controls …
{hint: left / logic}
Thought, language, logic, details and math
Right hemisphere controls
Functions at a subconscious level. Intuition, tone and reflection, perception. Your gut feeling.
Contra lateral specialization refers to how the two sides of your brain function. Together. The right side controls the left and likewise the left side
Control the right
Genotype is your …
Genetic makeup
Phenotype is your
Observable characteristics as a person.
The nervous system is composed of two basic feel types:
- Glial Cells
- Neurons
Neurons have what kind of membrane?
Semipermeable
Chemicals (or Medication) that mimics a neurotransmitter at the receptor site
Agonist
Chemicals that block, or impede the normal activity of a neurotransmitter at the receptor
Antagonist
The thalamus is the center piece of your brain. Is it your brains ____ relay station
{hint: Thalamus - Thesaurus)
Information
The ______ of a neuron contain synaptic vesicles that house neurotransmitters
{hint: don’t push my buttons)
Terminal buttons.
Psychotropic medication are drugs, that restore ______ balance.
Neurotransmitter
Homeostasis is a state of
Equilibrium in which biological conditions are maintained at optical levels.
What is the sense associated with the temporal lobe?
Audition
The medulla controls mainly three things. They are
- Breathing
- heart rate
- Blood pressure
