Science Flashcards
Dendrites
Dendrites receive signals and integrate them
Cell body
Cell body processes and regulates signals
Axon
Axon transmits signals to other cells
Terminal buttons
Terminal buttons release neurotransmitters to other cells
Sensory neurons
Sensory neurons carry signals from sensory receptors to the CNS
Moto neurons
Motor neurons carry signals from the CNS to muscles and glands
Interneurons
Interneurons carry signals between neurons within the CNS
CNS
CNS includes the brain and spinal cord
PNS
PNS includes nerves that connect the CNS to the rest of the body
Cerebrum
Cerebrum controls movement, sensation, perception, and thought
Cerebellum
Cerebellum coordinates muscle movements and balance
Brainstem
Brainstem regulates basic functions such as breathing, heart rate, and blood pressure
Nervous System
Nervous system uses electrical and chemical signals to transmit information
Endocrine System
Endocrine system uses hormone secretion to transmit information
Terrestrial ecosystems
deserts, forests, grasslands
Aquatic ecosystems
freshwater, marine
Producers
plants, algae
Consumers
animals, fungi
Decomposers
bacteria, fungi
Abiotic factors
Temperature
Light
Water availability
Soil composition
Thermoregulation in animals
e.g. sweating, hibernation
Camouflage in animals
e.g. changing color, hiding
Food Web
A food web is a network of feeding relationships between organisms in an ecosystem
Voltage source
Inductors (stores magnetic energy)
batteries, generators
Resistors
resistive materials like copper wire
Capacitors
stores electrical energy
