Q

Spinal Reflex Arc

A

A spinal reflex arc is a fast reaction to something, like pulling your hand away from a hot stove. It works without your brain thinking about it; the signal goes to your spinal cord and back to your muscles really quickly to protect you.

Q

Withdrawal

A

The discomfort and distress that follow the discontinued use of an addictive drug

20
Q

Parasympathetic Nervous System

A

“Bring you back down”
Functions to calm the person “Rest & Digest”
Reduces body arousal, energy, decreases blood sugar, increases blood flow to the digestive organs, decreases heart rate

21
Q

Autonomic Nervous System

A

Regulates involuntary and unconscious actions

Breathing, blood pumping through veins, digestion, heartbeat, work of other internal organs, blinking

22
Q

Central Nervous System

A

This coordinates the actions and interactions of the brain and spinal cord which is your body’s main control center.

-largest part of the nervous system
-the spinal cord is the information highway and connects the PNS to the brain

23
Q

Somatic Nervous System

A

Transmit signals from your brain to the skeletal muscles to allow VOLUNTARY movement
-Responsible for carrying sensory and motor information to and from the central nervous system

24
Q

Acetylcholine

A

Chemical Messenger in the body
It’s a neurotransmitter that helps transmit signals between nerve cells. It plays a key role in various functions, including muscle movement, memory, and attention. Essentially, it helps your brain and body communicate effectively.

25
Q

GABA

A

Neurotransmitter in the brain. Its main role is to inhibit or calm down nerve activity. This helps regulate anxiety, mood, and stress, promoting relaxation and a sense of well-being. Think of it as a natural brake system for your brain!

26
Q

Serotonin

A

Serotonin is a chemical in the brain that helps regulate mood, sleep, and appetite. It’s often called the “feel-good” neurotransmitter because higher levels are associated with feeling happy and calm. It plays a big role in your overall emotional well-being!

27
Q

Melatonin

A

Melatonin is a hormone that helps control your sleep-wake cycle. It signals to your body when it’s time to sleep, usually when it gets dark outside. Think of it as your body’s natural sleep helper!

28
Q

Refractory Period

A

The refractory period is the time after an event during which a cell or body part can’t respond to another stimulus.
EX: After a muscle contracts, it needs a brief period to recover before it can contract again. This ensures that muscles can rest and avoid fatigue during repeated use.

29
Q

All or Nothing Principal

A

The all-or-nothing principle means that when a neuron gets enough signal, it will fire completely, or not at all. There’s no halfway—it’s either a full signal or nothing!

30
Q

Resting Potential

A

Resting potential is the state of a neuron when it’s not active. It has a slight negative charge inside compared to the outside, like a battery waiting to be used. This setup allows it to send signals when needed.

31
Q

Reuptake

A

Reuptake is the process where a neuron takes back chemicals (neurotransmitters) it has released. This helps to clear the signal and recycle the chemicals for future use, like cleaning up after a party!

32
Q

Sleep Apnea

A

“Stop Breathing”: Chronic medical condition where the affected person repeatedly stops breathing during sleep.
These episodes last 10 seconds or more and cause oxygen levels in the blood to drop or awakenings from sleep

33
Q

Sleep/wake cycle - Circadian Rhythm

A

An out-of-sync sleep/wake cycle
The sleep/wake cycle, or circadian rhythm, is the body’s natural 24-hour clock that regulates when you feel awake and when you feel sleepy. It’s influenced by light and darkness, helping you stay in sync with day and night. This rhythm affects sleep patterns, energy levels, and other bodily functions.

34
Q

REM Paralysis

A

“Waking Nightmare”: The presence or persistence of features of rapid eye movement (REM) sleep during the transition into or out of sleep

35
Q

Narcolepsy

A

“Sleep Attack”: Sleep disorder in which a person falls immediately into REM sleep during the day without warning

Narcolepsy is a genetic disorder, usually a trigger is an intense emotion

36
Q

Nature

A

INHERITED characteristics
All of the genes and hereditary factors that influence who we are—from our physical appearance to our personality characteristic

HEREDITARY

37
Q

Nurture

A

Environmental factors that impact who we are.
-childhood experiences
-peer pressure
-social relationships

ENVIRONMENT

38
Q

Eyeball - Cones. Rods, Retina,

A

CONES: Function in bright light.
Allow us to see colors.
Provide sharp, detailed vision

RODS: Function in low light (night vision).
Do not detect color, only shades of gray.
Provide peripheral and motion detection.

39
Q

Ear - Pitch of the sound, Absolute threshold, Frequency of the sound wave,

A

Highness or lowness of sound, minimum intensity of a sound that a person can hear, number of waves that pass a point in one second

40
Q

Sensory Adaptation

A

Sensory adaptation is when your senses get used to something and stop noticing it as much. For example, if you smell something strong, you might notice it at first, but after a while, you don’t smell it anymore. It helps you focus on new things instead of constant ones.

41
Q

Absolute threshold

A

Absolute threshold is the quietest sound or faintest light that you can notice half the time. It shows how sensitive your senses are.

42
Q

Opponent-process theory

A

Opponent-process theory says we see colors in pairs that cancel each other out. For example, red and green are opposites. If you look at one color for a long time and then look away, you might see the opposite color as an afterimage.

43
Q

Mean

A

average set of numbers, add them all up then divide by how many numbers there are

44
Q

Median

A

middle of the numbers- order them in least to greatest
If there’s an even number, you take the two middle numbers, add them together, and divide by 2.

45
Q

Mode

A

frequent number- multiple 2s in a set, etc..
there can be no mode

46
Q

Cerebral Cortex

A

“Gray Matter”
Distinctly human traits including higher thought, language, and human consciousness as well as the ability to think, reason and imagine all originate in the cerebral cortex.

47
Q

NOTE FOR ME

A
