Sleep
This is the most basal organism that has been found to sleep, but be careful or it might sting!
Jellyfish
The relevant gradient of a neuron is similar to a banana in the ocean. Therefore, this ion would be most present in a neuron at rest.
Potassium
Endocrine glands produce these signaling molecules typically associated with teens in puberty, that are transported through the body to regulate behavior.
Hormones
Skeletal muscles are these types of muscles, which are less powerful and used for rapid contractions
Striated muscles
Trade-offs exist because there is a limited amount of energy, time, space, and nutrients an organism can use. These collective terms are referred to as...
resources
The term given to the condition where a person becomes unable to sleep for long periods, and eventually ends in their death.
Fatal familial insomnia
These types of synapses use neurotransmitters which can amplify or change a signal
Chemical synapse
The three basic classes of hormones are lipid-derived, amino acid-derived, and this third class.
Peptide hormones
The term pennate muscle fiber orientation describes parallel muscle fibers that give off the appearance of this outer protective layer of many animals
Feathers or feathery
Endothermy vs. ectothermy
flight vs running (locomotion)
etc...
This stage of sleep is characterized by fast breathing, higher heart rate, and more dreaming than usual. Not to be confused with the rock band.
REM sleep
Run! You are being chased by a dog down the street and this portion of the autonomic nervous system is now likely activated.
Sympathetic nervous system (Fight or flight)
Glucagon, a hormone that regulates blood glucose when levels are too low, is secreted from these cells in the pancreas. Think Greek!
The theory proposed to explain how muscles contract.
Sliding-filament theory
The process in which the product of physiological cascade stops further production of itself is referred too as.
Negative feedback loop
The ontogenetic hypothesis, proposed for why animals may sleep states that it is crucial in order to form these types of connections.
Neural connections
The rising phase in a neuron is caused due to the influx of this ion.
Sodium ion
This "fight or flight" neurotransmitter/ hormone is used to open up a person's airway during an allergic reaction.
epinephrine
Calcium ions in muscles are stored and released from this membrane bound organelle.
If the body strays too far out of homeostasis, enzymes may experience this process, meaning they break down and lose function
Denaturing
Term for how we humans sleep, that describes how both sides of the brain are not awake.
Bihemispheric
SSRI medicines are known to help reduce anxiety and depression. They are known to work due to a contract of this specific hormone in the synaptic cleft.
Serotonin
This hormone is commonly referred to as the "stress hormone".
Cortisol
After an animal dies the muscle cells run out of ATP. As a result the body will experience this stiffening phenomenon.
Rigor mortis
While a conformer tolerates a wider homeostatic range, this type of animal must keep its body within a narrower range.
Regulator
