Coordination In Human Flashcards
Effects of Adrenaline horomone
Increase heart rate
More blood to muscle
Fof More oxygen and glucose to muscle
For More aerobic respiration , for more energy
Breath rate increase for more oxygen
Blood glucose level increase
Pupil dialted to see better
Stimliu
Change In environment
Receptor
Specialized cells that detect change in environment
Effector
Part of the body that produces the response
Example of nerves
Central nervous system
Perephrial nervously system
Example of cns
Brain and spinal cord
Function of sensory neuron
Transmit electric impluses from receptor to cns (brain and spinal cord)
Function of relay
Transmitted electrical impulse from sensory to motor through synpase
Function of motor
Transmit nerve impluse from cns to muscle and glands
Coordinated response require
Sitmulus
Receptor
Effector
Types of receptors
Light
Touch and heat
Chemical
Sound
What mean transducers
Change one form of energy to another
Synapse
Gap between 2 neurons
Say mechanism of transmission of nerve impluse across synapse
Impluse arrive down axon of 1 neuron
Impluse stimulates the release of neurotransmitter
Neurotransmitter diffuse across synaptic gap
Neurotransmitter attach to receptor on membrane of second neuron intating another electrical impluse
What mean reflex action
Involuntary rapid response to stimulus which often protect body
What is meant by coordination
Organisms are able to respond to changes in environment for survival
Corena
Refract light
Pupil
Allow light in eye
Iris
Change size of pupil and control amount of light enter eye
Susponsry ligament and ciliary muscle
Change shape of lens and shape in accomidation
Retina
Light receptor
has rods and cons
Detect light
