Chapter 3 Flashcards
(24 cards)
Nuerons
Nerve cells
Cell Body vs Dendrites vs Axon
- Nucleus and organelles
- Receive signals
- Transmits nerve signals
Central Nervous System vs Peripheral Nervous System
Brain and spinal cord vs sensory and motor nerves
Sensory neuron vs sensory receptor
Take to brain vs converting stimulus into nerve signals
Motor neuron
Takes signal to the effector
Effectors
The part of the body responding
Photoreceptors
Stimulated by light energy
Rods vs Cones
Night, peripheral, and motion vs color
Synapse
Gap that a nerve signal must cross to reach the next neuron
Nueroethology
Study of neurobiological causes of behavior
Hippocampus vs Mushroom bodies
Memory function in vertebrates vs spatial learning in invertebrates
Endocrine glands
Secrete hormones
Hormones
Chemical signal that affects other glands/tissues
Target Cells
Receptors for the hormone
How does a nerve impulse work
Sensory receptors convert stimulus into nerve signal, sent to next neuron via axon crossing synapse
What is nueral plasticity and why is it adaptive
Ability to alter structure and physiology in response to behavior, allows them to learn
How does the endocrine system work with the nervous system
Maintain homeostasis
Why are hormones secreted into the bloodstream
To reach their target cells
2 ways that hormones are controlled
Other hormones or the nervous system
Positive vs negative feedback regulation of hormones
Negative feed back gives you what you need
Positive feed back gives until the job is done
Adrenaline
Fight or flight
Cortisol
Stress induced by glucose
Testosterone vs Prolactin
Aggressive vs Maternal behavior
Vasopressin
Parental care
