Nervous and Endocrine System Flashcards
conduits for cell to cell communication
- neurons
- hormones
electrical stimulus
neurons
chemical messengers
hormones
hormones are produced by the ____
glands
produced by the pancreas that is needed to regulate blood glucose level
insulin
local regulator cells means that the two cells are _____ to each other
adjacent
similar to neurotransmitters but quite bigger
neuropeptides
chemical messengers in insects
pheromones
major glands of the nervous system
- hypothalamus
- pituitary gland
- parathyroid
- thyroid gland
- adrenal glands
- pancreas
- ovary
- testes
brain region controlling the pituitary gland
hypothalamus
secretes many different hormones, some of which affect other glands
pituitary glands
affects metabolism
thyroid glands
help regulate level of calcium in the blood
parathyroids
help trigger the fight-or-flight response
adrenal gland
regulates the sugar level in the blood
pancreas
secretes female sex hormones
ovaries
secretes male sex hormones
testis
functions of nervous system
- controlling the body and communication for its parts
- coordinate the functions of the other organs and organ systems
types of neurons
- sensory neurons
- motor neurons
- interneurons
relay the info from the environment to the body
sensory neurons
relay info from the cell to the muscle
motor neurons
serve to coordinate the motor and sensory neurons
interneurons
functional division of the nervous system
- CNS
- PNS
includes the brain and spinal cord
central nervous system
includes nerves
peripheral nervous system
embryonic region of the cns
ectoderm
2 surface of the ectoderm in the cns
- epidermis
- dorsal part that becomes the brain & spinal cord
process of brain and spinal cord formation
neurolation
protects the brain and spinal cord
meninges
