Brain Bee Part 3

Front 1

Brainstem

Back 1

Controls respiration and heart rhythm. Where forebrain sends information to and from spinal cord and peripheral nerves

Front 2

Broca's area

Back 2

Located in frontal lobe of left hemisphere. Important for speech production

Front 3

Catecholamines

Back 3

Neurotransmitters dopamine, epinephrine and norepinephrine. Active in brain and peripheral nervous system

Front 4

Cell body

Back 4

Part of neuron that contains the nucleus

Front 5

Cerebrum

Back 5

Largest part of brain. Important in thinking, perceiving, planning and understanding language

Front 6

Cerebellum

Back 6

Part of hindbrain. Helps controlling motor movement through connections to pons, medulla, spinal cord and thalamus

Front 7

Cerebral cortex

Back 7

Sheet of tissue covering outermost layer of the cerebrum

Front 8

Cerebrospinal fluid

Back 8

Found in ventricles of the brain and the central canal of the spinal cord

Front 9

Circadian rhythm

Back 9

Cycle of behaviour or physiological change lasting around 24 hours

Front 10

Cochlea

Back 10

Part of inner ear that converts sound into electrical potentials

Front 11

Cognition

Back 11

The process of gained knowledge being used for problem solving and comprehension

Front 12

Cone

Back 12

Receptor cell for vision found in the retina. Used mostly for daytime vision and is sensitive to colour

Front 13

Corpus callosum

Back 13

Bundle of nerve fibres linking the left and right hemispheres

Front 14

Cortisol

Back 14

Hormone made by adrenal cortex. Secreted before dawn and readies body for the activities of the day

Front 15

Cranial nerve

Back 15

Nerve that carries sensory and motor output for the head and neck region

Front 16

Declarative memory

Back 16

Ability to learn and consciously remember everyday facts and events

Front 17

Depression

Back 17

Psychiatric disorder, characterised by sadness, pessimism and abnormalities in sleep

Front 18

Dendrite

Back 18

Extension of the neuronal cell body. Receives and integrates information from other neurons

Front 19

Dopamine

Back 19

A catecholamine neurotransmitter found in three circuits in the brain. One that regulates movement, one important in cognition and emotion, and one that regulates the endocrine system

Front 20

Down syndrome

Back 20

Occurs when extra copy of chromosome 21 is present in the egg

Front 21

Endocannabinoids

Back 21

Lipid derived messengers. Control the release of neurotransmitters, usually inhibiting them. Important in controlling behaviours

Front 22

Electroencephalography (EEG)

Back 22

Records electrical activity in the brain in response to various stimuli and activities

Front 23

Endocrine gland

Back 23

Secretes hormones directly into bloodstream to regulate cellular activity of other organs

Front 24

Endorphins

Back 24

Neurotransmitters in the brain that produce similar effects to morphine
