Feeling Nervous?
The main processes of the Central Nervous System are processing sensory information & ______________.
What is coordinating a response?
This lobe of the brain is associated with personality & decision making
What is the frontal lobe?
This 2-part gland is known as the "master gland" of the endocrine system
What is the pituitary gland?
This type of sensory receptor is able to detect pressure in the skin & vibration in the ear
What is a mechanoreceptor?
This naturally-occurring hormone helps to regulate mood, and in high doses has been associated with an increased risk of cancer (but a decreased risk of heart disease)
What is estrogen?
This type of neuron carries information from the PNS to the CNS
What is a sensory (afferent) neuron?
This part of the brain allows you to perform complex tasks like driving or knitting on "autopilot" - assuming you've mastered those tasks at some point
What is the cerebellum?
This hormone helps to regulate sleep/wake cycles
What is melatonin?
This structure or layer in the eye contains the photoreceptors necessary to process vision
What is the retina?
High levels of cortisol have been linked to these effects on a person's mood
What are anxiety and depression?
This insulating layer helps conduct action potentials more quickly in some neurons
What is the myelin sheathe?
You activate this part of your brain in order to make sense of the words you hear someone else saying
What is Wernicke's Area?
DAILY DOUBLE!!
Pancreas, Insulin
The specific role of acetylcholine is this.
What is stimulating muscle contractions?
This hormone increases production during competition; simply WATCHING an intense competition may be enough to produce it in your body
What is testosterone?
A neuron will fire an action potential only if an influx of ions allows it to reach it its _________________.
What is threshold potential? (-55mV)
This neurotransmitter is primarily associated with feelings of pleasure
What is dopamine?
Sometimes called the "cuddle drug", this hormone has been associated with bonding and trust in animals
What is oxytocin?
This type of muscle is not under conscious control; it lines the internal organs including our digestive organs
What is smooth muscle?
Hormones travel through the bloodstream until they reach specific _________, where they can bind to cause physiological changes in the body
What are target cells?
DAILY DOUBLE!!
Sensory Neuron, Interneuron, Motor Neuron
This type of learning occurs as synapses between certain neurons are strengthened & increased, improving their connection & likelihood of firing together
What is long-term potentiation?
This is the major functional difference between steroid hormones & peptide hormones
What is steroid hormones are hydrophobic & peptide hormones are hydrophilic? OR What is steroid hormones can enter the cell to bind receptors & peptide hormones bind to the outside of a cell's membrane
In order to stimulate a muscle contraction, a motor neuron must release neurotransmitter at the _________ - the location where it interfaces with a muscle fiber
What is the synaptic cleft?
This endocrine disruptor was among the first studied and discussed on a national scale; its use was eventually banned thanks largely to Rachel Carson's activism and her book Silent Spring
What is DDT?
