: made up of endocrine glands that release hormones directly to the bloodstream
are organic molecules made up of an assorted chemical composition which act on specific cells called
stimulate target cells to coordinate, control and regulate different organs.
links the nervous system with the endocrine system. It produces hormones that control the
hypophysis (or pituitary gland)
to make other hormones.
Hormones are secreted in small quantities and their production is controlled by feedback mechanisms.
(activate other glands).
(promotes a lengthening of the bones and growth in general).
(stimulates the utilisation of glucose by muscles and tissues).
(stimulates the conversion of glycogen to glucose).
(regulates the amount of calcium and phosphorus in the blood)
(prepares the body to work)
(produce and maintain male sexual traits).
(produce and maintain female sexual traits).
(allows the embryo to be implanted in the uterus).
transmit the information
most cells specialise
: long extension made u of cytoplasm / carry nerve impulses
: short branched extensions of the cell body that receive nerve impulses from other neurons
: nucleus and organelles
: transmit the signals from the nerve centres to the effector organs
: connect the sensory neurons to the motor neurons (brain and spinal cord)
: transmit information from receptors to the most important nerve centres
: generated and transmitted by neurons. When a neuron is stimulated, some electrical changes originate in the membrane and these transmit the electric signal from the dendrites towards the axon.
: connections between neurons
: the gap between neurons
: are substances collected in the small vesicles at the end of the axon. They are released to the synaptic clef when the nerve impulse reach the end of the axon and the vesicle breaks up
Interprets the information and prepares adequate responses
Transfers the necessary signals to the effectors organs
Receives information transmitted by the sensory organs
Coordinates all the organs
Carries out intellectual and mental functions
Responsible for emotions and feelings
