Q

Describe and explain all the ways the hypothalamus prepares your body for stresses it may encounter

A

When the hypothalamus senses stress it sends signals to the adrenal medulla to release epinephrine or the pituitary to release a fight or flight response

Q

The functions and structures of the brainstem

A

Medulla oblongata-vital to the bodies functions (breathing,heart rate)

Mesencephalon-hearing,eye movement, vision, body movement

Cerebellum-movement and posture

Pons-relay center from the brain to cerebellum

17
Q

Describe hemianopia and akinesia

A

Hemianopia is blindness in half of the eye

Akinesia is the lack of voluntary movement due to lack of dopamine activity

18
Q

If you were a doctor and observed dysarthria in the patient, what what is the possible areas of the brain affected, and why?

A

Dysarthria affects the cerebellum, the cerebellum coordinates motor involuntary movement

19
Q

In class we learned about pathologies of the cerebellum, the pons and the mesencephalon. However, in general pathologies of the medulla oblongata are more serious why?

A

Medulla pathologies are more serious because it controls vital organs

20
Q

Explain in detail how the basal ganglia controls subconscience muscle movement

A

The basal ganglia controls “subconscious”. Muscle movement beginning with the cerebral cortex sending messages to the basal ganglia. Then the basal ganglia sends a message to the cortex by going through the Thalamus then the cerebral cortex send messages so the motor neuron and interneuron

21
Q

A sleep cycle consists of five steps, which are in turn divided into two categories: REM sleep and non-REM sleep. REM sleep, or rapid eye movement sleep, occurs toward the end of each cycle and is typically the stage for our most lucid dreams. Conversely, non-REM sleep is generally lighter and dreamless, save for a few fragmentary images here and there

A

At this stage, sleep is very light and can easily be disrupted. Mental activity begins to slow down, with brain waves

eye movement stops and brain waves become slower, with alpha activity shutting down entirely

22
Q

Explain the functions of the thalamus. How does Thalamus specifically perform these functions?

A

The functions of the Thalamus is to relay motor and sensory to the cerebral cortex

23
Q

What are three possible pathologies of the thalamus? What causes these pathologies? How are these pathologies connected to the function of the thalamus?

A

Three pathologies of the thalamus are Ataxia, Dejerine ,roussy syndrome

24
Q

What are the basic functions of the limbic system?

A

The limbic system supports a variety of functions including epinephrine flow, emotion, behavior, motivation, long-term memory

25
Q

What is capgras syndrome?

A

Disorder that leads someone to believe their family member have been replace. It is caused when their hippocampus and the amygdala. The disorder leads someone to believe their family members have been replaced by imposters

26
Q

What is the difference between random error and bias?

A

The difference between bias and errors is that errors are unknown and unpredictable. Bias is when the scientist performing the experiment influence the results.

27
Q

Parts of the neuron:

A

Dendrites- receive incoming signals from other neurons

Soma- body of the cell and it determines when the cell fires

Terminal buttons- releases chemical
neurotransmitters to another neuron

Axon- conducts signal called action potentials and has a myelin sheath which covers the axon.

28
Q

Explain why sciences have not been able to duplicate the complexity involved in human movement. Be careful not to just express your opinion. You must provide a solid evidence!

A

Scientist can not duplicate the complexity involved in the human brain because it sends signals through neurons which tell parts of the body to move whether it is voluntary or involuntary movement.

29
Q

What are the parts of the cerebrum and their functions?

A

Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
Occipital Lobe- associated with visual processing
Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech

30
Q

Explain the functions of all the parts of a neuron.

A
  • Soma- the cell body
  • Dendrites- recieves message from other cells
  • Axon- passes messages away from the cell body to other neurons, muscles and glands
  • Action Potential- electrical signal traveling down the axon
  • Myelin Sheath- covers the axon of some neurons and helps speed neural impulses
  • Terminal button- forms junctions with other cells
31
Q

Compare and contrast an action potential with an electrotonic potential.

A
  • Electrotonic triggered by stimulus
  • Action triggered by threshold
  • Electrotonic has no refactory period
  • Electrotonic chemical gated ion channels
  • Short distance travel
  • Action potential voltage gated ion chanels
  • Long distance travel
32
Q

Why is the outside of a nerve cell always more positive than the inside?

A

Because of the sodium potassium pump , so everything can be equal, if it wasnt more positive than it wouldnt be equal and the sodium potassium pump will not function

33
Q
  1. What are the requirements for a good scientific graph?
A

Data table, variables, IV goes x axis , dependent variable goes on vertical axis , scale, number and label each axis, plot the data,

34
Q
  1. Why do chlorine and potassium cause inhibition of nerve transmission?
A

-They cause inhibition to stop the transmission to keep going, if chloride gets in it becomes more negative and if it becomes more negative it can never get to -55 which it need in the axon hillock in order for the whole prcess to start again

35
Q
  1. Why do chlorine and potassium cause inhibition of nerve transmission?
A

-They cause inhibition to stop the transmission to keep going, if chloride gets in it becomes more negative and if it becomes more negative it can never get to -55 which it need in the axon hillock in order for the whole prcess to start again

36
Q

Where are voltage-gated ion channels located? Where are ligand-gated ion channels located?

A
  • voltage gated ion channels are located in the axon and the ligand-gated cahnnels are located at the terminal end
37
Q

Compare and contrast an electrical gradient with a concentration gradient

A
  • when something goes from high to low and concentration is molecules, electrical is ions
