A
nerve cells that send messages all over your body to allow you to do everything from breathing to talking, eating, walking, and thinking
2
Q

the pathway by which a reflex travels—from the stimulus to sensory neuron to motor neuron to reflex muscle movement
3
Q
neurotransmitters
A
endogenous chemicals that allow neurons to communicate with each other throughout the body
4
Q
peripheral nervous system
A
part of your nervous system that lies outside your brain and spinal cord
5
Q
central nervous system
A
part of your nervous system that is your brain and spinal cord
6
Q
forebrain
A
controls body temperature, reproductive functions, eating, sleeping, and the display of emotions
7
Q
midbrain
A
the smallest portion of the brainstem (about 1.5 cm) and its most cranial structure and is associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation, acting as a sort of relay station for auditory and visual information
8
Q
hindbrain
A
a developmental categorization of portions of the central nervous system in vertebrates; includes the medulla, pons, and cerebellum; supports vital bodily processes.
9
Q
cerebrum
A
the largest part of your brain, and it handles a wide range of responsibilities; instrumental in day-to-day activites
10
Q
spinal cord
A
a long, tube-like band of tissue connecting your brain to your lower back
11
Q
lateralization of cortical functions
A
the left and right sides of the brain are specialised to attend to different information, to process sensory inputs in different ways and to control different types of motor behaviour
12
Q
methods of studying the brain
A
fMRI uses very powerful magnets and can localize brain activity changes to regions as small as one cubic millimeter
EEG measures brain waves
PET shows how the brain and its tissues are working
13
Q
neurotransmitters and behavior
A
neurotransmitters play some role in behavior, including the neuropeptides; most commonly implicated in behavior modulation are the small molecular transmitters norepinephrine, dopamine, and serotonin.
14
Q
components of the endocrine system
A
multiple glands throughout the body
15
Q
endocrine system and behavior
A
endocrine system releases hormones, and hormones impact the systems that cause changes in our behavior, including changes in what we might call biological motivations
16
Q
behavioral genetics
A
the study of the manner in which genetic variation affects psychological phenotypes (traits), including cognitive abilities, personality, mental illness, and social attitudes.
17
Q
genes
A
the basic physical and functional unit of heredity
18
Q

A
consistent individual differences in behavior that are biologically based and are relatively independent of learning, system of values and attitudes

the passing on of traits from parents to their offspring
20
Q
adaptive value of traits and behavior
A
represents the usefulness of a trait that can help an organism survive in its environment
21
Q
nature and nurture
A
describes the question of how much a person’s characteristics are formed by either “nature” or “nurture;” “nature” means innate biological factors (namely genetics), while “nurture” can refer to upbringing or life experience more generally.
22
Q
experience and behavior
A
experience has a paradoxical effect on intention-behavior consistency; in some studies, greater experience is associated with weaker intention-behavior relations (due to habit formation), whereas in other studies experience strengthens the relationship between intention and behavior (by stabilizing intentions).
23
Q

A
the changes that occur in an organism’s body as it grows and matures

27
psychoanalytic perspective of personality
Freud's theory: our unconscious self drives our personality
- id = unconscious desires
- ego = reasons between id and superego to make decisions
- super-ego = moral self
28
humanistic perspective of personality
humans have free will and humans can develop themselves to reach their highest potential/self-actualization; we are inherently good and self-motivated to improve
- eg. Maslow's hierarchy of needs
- eg. Carl Rogers: qualities needed for self-actualization are nurtured early in life in a growth-promoting climate (the person has to be genuine and receive acceptance)
29
trait perspective of personality
considers the personality of an individual and the number of traits they have
30
social cognitive perspective of personality
our personalities are fluid and change over time and according to who we are around; they are mainly the results of behaviors that are heavily influenced by observing and judging the actions of other people.
31
biological perspective of personality
emphasizes the internal physiological and genetic factors that influence personality; personality traits manifest through biology and there is a link between personality, DNA, and processes in the brain; personality is inherited
- eg. evolutionary biological theory: personality is related to the costs associated with passing down genetic material
32
behaviorist perspective of personality
view personality as shaped by the reinforcements and consequences outside of the organism; people behave consistently based on prior learning
33
situational approach to explaining behavior
suggests that the way in which people behave will depend on the situation that they are in and the environmental stimulus which surrounds them

164
fertilization
1. the sprem binds to the zona pellucida
2. the acrosome reaction occurs where the enzymes from the acrosome are released and start digesting the zona pellucida allowing the sperm to get closer to the egg
3. when the sperm and egg touch, the cortical reaction occurs where the cortical granules in the egg are ejected and start eating away the zona pellucida to block polyspermy from happening
4. the egg cell and sperm cell fuse and the DNA from the sperm cell enters the egg cell and the genetic material fuse
165
polyspermy
when multiple sperm bing to an egg cell
166
zygote
right when the sperm cell and egg cell's genetic material fuse, they form a zygote

168
morula
32-cell system that is still in the zona pellucida and hasn't grown in size at all (is the same overall size as a zygote)
169
compaction

cells on the outside of the morula
172
embryoblasts

175
blastocyst
the name of the cell cluster that forms from the morula
176
blastulation
once a blastocyst forms, the zona pellucida starts to be broken down and eventually disintegrates; the cells inside the blastocyst start to differentiate more, and a cavity forms inside the embryoblast, and the bottom layer of cells in the embryoblast starts to differentiate
177
amniotic cavity
empty space in the embryoblast inside the blastocyst
178
