Nervous and Endocrine system Flashcards
Which hormone is secreted by the adrenal gland?
adrenaline
Which endocrine gland secretes the horomones insulin and glucagon?
pancreas
What do you call the hormone that decreases blood glucose level?
insulin
All endocrine glands secrete hormones directly into the ____
bloodstream
Hormones are important to maintaining homeostasis because they cause (specific/nonspecific) response from target cells.
specific
In a neuron, impulse travels from the dendrites -> __ __ -> ___
cell body, axon
A nerve impulse travels from the axon terminal of one nerve cell to the ___ of another nerve cell
dendrite
Impulse travels from the dendrites to the ____ _____ then to the axon
cell body
Which sense receptor is classified by taste and smell stimuli
chemoreceptor
pin prick -> sensory neurons -> _____ (spinal cord or brain) -> ____ neuron -> muscle contraction -> pull finger away
interneuron, motor neuron
______ neurons carry impulses from outside of the body to the CNS (brain and spinal cord.)
sensory
____ are the “antennae” that extend from a neuron and that receive information from other cells or outside the body.
dendrites
What is wrapped around the axon that allows the impulse to travel faster?
myelin sheath
What is the space between two neurons called?
synapse
Once the impulse reaches the axon terminal of the presynaptic nerve cell, chemical messengers called _____ are released into the synapse.
neurotransmitters
Reflex responses are controlled in your______ _______.
spinal cord
Which type of feedback is more common in maintaining homeostasis.?
negative feedback (regulating body temperature)
if a person does not produce enough insulin, this may result in a (low/high) blood glucose level and cause diabetes
high
Which type of feedback is less common and creates imbalance in the body?
Positive feedback (adrenaline rush)
Which part of a neuron carries signals away from the cell body?
axon
An involuntary and automatic response to a stimulus is called a ____
reflex
Which neuron conducts impulses from the brain/spinal cord to the body parts?
motor neurons
Which nerve cell relays impulses between sensory and motor neurons?
interneuron
The central nervous system (CNS) is made of the ____ and ____.
Brain and spinal cord
Label the parts of the neuron
Cell body, dendrite, axon, axon terminal
What is the gap between the myelin sheath called?
nodes of ranvier
what is the myelin sheath made up of?
schwann cells
List the three types of neurons
sensory neuron, inter neuron, motor neuron.
Which brain controls reading, writing, and analyzing
left
Which brain controls verbal and nonverbal artistic abilities
right
which sense contributes to the eye and vision
photoreceptors
which sense contributes to ears and hearing
mechanoreceptors
what sense detects temperature
themoreceptors
What is the regulation and maintenance of the internal environment?
homeotasis
homeostasis is maintained by ______
feedback loops
