Ch26, p1 Hormones and endocrine system Flashcards
26.1,2,3
How our body organs can communicate with each other?
By sends signals
How many types of signals that sends in our body?
Two types(electrical and chemical signals)
There are two types of signals that are sends in our body, what are they?
Electrical signals and chemical signals
The chemical signals are called……
hormones
The hormones are secreted from…….
glands
There are a specific type of cells who are responsible for the secretion of hormones called ……
endocrine cells
The endocrine cells are made and synthesis and secrete ………
chemical signals (hormones)
Within the endocrine cells there are ……… which are turn store hormones
secretory vesicles
Are work like a storage of hormones?
secretory vesicles
What is the main function of secretory vesicles?
Stores hormones
When the secretory vesicles have or receive specific order such as stimulus come, what gonna happens?
Starts to release a hormones into the blood
If hormones reach every cell in the body, why do some cells respond to specific hormones?
Because of receptor ( they reach the target tissues or target cells that have specific receptor that bind to that hormone )
Every hormone have own key called……
receptor
What kind of signals that after stimulus comes they pass through a neurones until they reach the target tissues?
Electrical signals
In electrical signals transmission, starts with stimulus to pass from one neurone to another until reach target tissues but that target tissue should have a special ………between a neurones
junction
The type of signals that may travel long distance to reach target cells is………
both chemical and electrical signals
What the main function of junctions in electrical signals transmission?
Junctions are working as a connection between a neurones to allows to that signals passing between a neurones to reach a target tissues as a result of signals effect
The type of signals that reach the target tissues by travel distinct pathway along neurones by specialised junctions is………
electrical signals
The type of signals that are fast and last for short time is………
electrical signals
The type of signals that are gradual response and last longer is………
chemical signals (hormones)
The type of signals that reach the target tissues by travel through the blood to all body is………
chemical signals (hormones)
The adrenaline hormone from adrenal gland could be……
a)electrical signals
b)chemical signals
c)both of them
C) both of them
The right order for the hormonal signal……
reception ➡️ signal transduction ➡️ response
The type of chemical signal that pass directly through the cell membrane without a receptor is ………
lipid-soluble hormones
