17
Q

Function of the central sulcus

A

Separates the parietal and frontal lobes

18
Q

Function of the pons

A

Relays signals from the front of the brain to the cerebellum

19
Q

Function of the medulla oblangada

A

Breathing, sneezing, and swallowing (involuntary actions)

20
Q

Function of the spinal cord

A

Sends signals to a from the brain to the rest of the body

21
Q

Function of the hypothalamus

A

Maintaining homeostasis

22
Q

Function of the hippocampus

A

Regulates long term memory

23
Q

Function of the pineal gland

A

Sleeping and waking

24
Q

Function of the amigdala

A

Fight or flight response

25
Q

How would a breakdown of the central nervous system affect the body?

A

Muscles would not coordinate and respond to stimuli, everyday actions such as waking up and going to sleep would be gone, loss of senses, etc. (the CNS wouldn’t be able to communicate to the PNS or rest of the body)

26
Q

Function of the pituitary gland

A

Thirst and hunger

27
Q

What is communication

A

Sending and receiving messages to get a job done

28
Q

How does communication occur in machines and in the human body

A

PNS, CNS, nerves send signals

29
Q

What are gyri and sulci

A

Folds in the brain that carry oxygen and glucose to the brain

30
Q

Up and down arrows on the spinal cord represent

A

The flow of neurological nutrients being sent to the brain to be processed and interpreted

31
Q

The limbic system is responsible for

A

Storing memory and carrying out emotions and inner thoughts

32
Q

Phineas gauge suffered from ___ causing a difference in his ___

A

Damage to his frontal cortex; emotions and actions

33
Q

How do the PNS and CNS work together

A

The PNS picks up signals from the brain and sends these signals to the CNS to be processed

34
Q

How do scientists determine what parts of the brain are responsible for

A

MRI’s and dissections of people with specific issues

35
Q

What three things is the brain stem composed of

A

Midbrain, pons, and medulla oblangada

36
Q

What is a gyrus

A

The ridges and grooves of the brain

37
Q

What is the function of the limbic system

A

Controls emotion and motivation

38
Q

What parts of the brain can be found in the limbic system

A

Hypothalmus, hippocampus, amigdala

39
Q

What is a sulcus

A

The shallows of the brain that separate the gyri

40
Q

What is phrenology

A

The study of the skull believing that it is responsible for character
