Coordination and Response
Coordination in Animals
Stimulus
Receptors
the "sensors"
Effectors
The ones than contract when something is different. Example: Muscles
Animals need quick responses in order to survive. For example to gain foor or to avoid predators
the nerves and receptors make up the nervous system
Hormones, this method is slower but in part of the endocrine system
2 methods:
Coordination in humans
Neurones
contain the same basic parts of any animal cell: Nuclous cytoplasm and cell membrane, but it is "programed" to carry messages verry quickly
Axon: longest fibre
Dendrites: shrtest fibres and pick up electrical signals from other neurones nearby.
signals: nerve impulses.
Central nervous system (CNS)
peripheral nervous system (PNS)
Make up of nerves and receptors
its role is to coordinate messages that travel through the system (CNS)
Made up by neurones
When the receptor detects a stimul, it sends and electrical impulse to the brain in order to react and this are in charge to take this message to the appropiate effector.
Reflex arcs
Is basically the process in which impulses are being done by your own body. For example If your hand touches a hot plane, an impulse is picked up by a sensory receptor in your finger
sensory neurone: the cell in charge of carrying the message to the sensory receptor
