Neurons
This increases the strength of a nerve signal
This system is antagonistic to parasympathetic nervous
What is the sympathetic nervous system?
This receptor turns light into an action potential
What is a photoreceptor?
This type of hormone triggers signal transduction via a secondary messenger
What is an amino acid based hormone?
What is the cerebrum?
This fatty layer insulates neurons and speeds up the velocity of nerve signal transmission
What is the myelin sheath?
This system is responsible for our voluntary movement
What is the somatic motor system?
Chemoreceptors, Mechanoreceptors, Nociceptors, and are this type of receptor
What are General Sensory Receptors?
This loop helps our bodies maintain homeostasis by returning to a set point.
What is a negative feedback loop?
This region is response for our memory and feelings?
What is the limbic system?
As this proceeds, it passes from the resting state, through depolarization, repolarization, and hyperpolarization before returning to the resting state.
What is an action potential?
This phenomena will result in the suppression of the parasympathetic nervous system and can lead to a myriad of health issues like heart disease
What is stress?
These are the three outer layers of the eye
What are the fibrous, vascular, and pigment (retina) layers?
This condition is caused by low thyroid hormone and can result in weight gain
What is hypothyroidism?
These are the 3 layers of the meninges that protect the brain
What is the duramater, arachnoid membrane, and the piamater?
This is caused by a signal that is received by receptors, passes through the afferent neurons, is integrated in the spine, before triggering a signal through efferent neurons to our effector organs.
What is a reflex?
For us to be able to hear a sound, it must pass through the ear in this order
This region of the brain is the first critical stop for neuronal stimulation of the endocrine system
What is the hypothalamus?
This structure is responsible for maintaining our balance are we rotate our head.
What is the semicircular canals?
This is the period where a neuron cannot generate another action potential?
What is refractory period (hyperpolarization)?
The somatic nervous system innervates these by releasing the neurotransmitter ACh
What is skeletal muscle?
This fact makes our sense of smell different from others
What is the fact that our olfactory nerves send sends signals to the limbic system?
This gland is responsible for releasing mineral corticoids, glucocorticoids, and Gonadocorticoids
What is the adrenal gland?
This organelle is responsible for contain various substances insides the cell before releasing them through exocytosis
What are vesicles?
