brain

Question 1

frontal lobe

Answer 1

regulate executive function

Question 2

Pariental lobe

Answer 2

sensory function. receiving and processing sensory information.

Question 3

temporal lobe

Answer 3

auditory and language function

Question 4

occipital lobe

Answer 4

important role in everything that deals with vision

Question 5

cerebellum

Answer 5

“Small brain”
motor control and cognitive function

Question 6

Optic chiasm

Answer 6

location of where optic fibers from the eye cross

Question 7

The pharahippocampal gyrus

Answer 7

a part of the hippocampus which is involved in memory

Question 8

pons

Answer 8

a part of the brainstem and relays information between higher and lower levels of the CNS. its involved in sleep and vital functions.

Question 9

Olfactory bulb

Answer 9

involved in odor detection

Question 10

corpus collosum

Answer 10

communication between hemispheres

Question 11

brainstem

Answer 11

Pons and Medulla, they are involved in vital body functions such as heart rate and respiration.

Question 12

dorsal thalamus

Answer 12

placed close to the corpus collosum. receives almost all incoming information and relays it to the cerebral cortex

Question 13

Hypothalamus

Answer 13

involved in reproductive functions and plays a role in the control of homeostasis and balance etc.

Question 14

striatum

Answer 14

Consists of two (3) nuclei; The putamen and the caudate. The striatum coordinates multiple aspects of cognition, including both motor and action planning, decision making, motivation, reinforcement and reward perception.

Question 15

Basal Ganglia

Answer 15

consists of element of the striatum; caudate and putamen, but also globus pallidus. The basal ganglia receives input from the cerebral cortex and participate in the organization and guidance. of complex motor functions, important role in the reward system and supports the cognitive tasks of striatum.

Question 16

Nucleus Accumbens (NAc)

Answer 16

Also refferd to as the ventral striatum.

Connected to the reward system and release of dopamine.

Question 17

The amygdala

Answer 17

The emotional brain nucleus. Plays a role in a lot of functions, some of them being decision making, memory and fear are a few.

often considered part of a separate system known for its role in learning and memory, emotional reactions and motivated behavior.

also part of the limbic system.
damage amygdala makes it difficult to asses danger.

Question 18

The limbic system

Answer 18

The limbic system system is a part of a subcortical and cortical nuclei. Its involved in learning and memory emotional reactions and motivated behavior.

Ares in the system is: the amygdala, mammillary body, hypothalamus, but also cortical regions like the hippocampus and anterior cingulate cortex.

Abnomalities in the limbic system can cause severe amnesia or inadequate emotional reactions and social behavior.

Question 19

spinal nerve

Answer 19

Ventral and dorsal root joints

Question 20

Blood Brain Barrier (BBB)

Answer 20

Keeps out large molecules from entering the brain, terfore also protecting the brain from toxins. The barrier prevent free ionic and molecular traffic. Depending on the molecules, they can enter the brain or not: soluble in lipid = no entrance, not soluble in lipid = entrance (like glucose).

Question 21

Gastrulation

Answer 21

the process during embryonic development that changes the embryo from a blastula with a single layer of cells to a gastrula containing multiple layers of cells.

Question 22

Neurulation

Answer 22

refers to the folding process, that includes the transformation of the neural plate into the neural tube.

Question 23

Stages of neurodevelopment (7 stages)

Answer 23

1. cell birth/ neurogenesis
2. Cell migration
3. cell differentation
4. cell maturation (dendrite and axon growth)
5. Synaptogenesis (formation of synapses)
6. cell death and synaptic pruning
7. myelogenesis (formation of myelin)

Question 24

Symmetrical division

Answer 24

one progenitor cell devide into two equal progenitor cell

Question 25

Asymetrical division

Answer 25

one progenitor cell and one brain cell.

Question 26

Dendritic arborization

Answer 26

the formation or growth of dendrites and axons.

Question 27

Brain plasticity

Answer 27

The nervous systems potential for physical or chemical change that enhances its adaptability to environmental change and its ability to compensate for injury.
