coordination and response Flashcards
what do organisms have, what do they detect
ORGANISMS HAVE RECEPTORS AND DETECT STIMULI
WHAT REACTION IS NEEDED FOR ENZYMES TO WORK PROPERLY
METABOLIC REACTION
WHAT DO CNS CONSIST
BRAIN AND SPINAL CORD
WHAT DO NEURONES CARRY
ELECTRICAL IMPULSES
WHAT ARE THE 3 TYPES OF THE NERVOUS SYSTEM
SENSORY, RELAY, MOTOR
What is the order of the nervous system
receptors–> CNS-CNS-CNS-CNS-Effectors
what is a synapse
connection between 2 neurons
what is the order for the nervous system in reflexces SRCER
stimulus, receptor, coordinator, effector, response
what are receptor cells
special cells that detect stimuli
What happens in bright light
circular muscles contract, radial muscles relax, pupils constrict
what happens in dim light
circular muscles dilate, radial muscles contract, and pupils dilate
what happens when focusing on a far object
ciliary muscles relax, suspensory ligaments tighten, lens is pulled thin
what happens when focusing on a close object
cillary muscles contract,suspensory ligaments slacken, lens becomes fatter
what do the endocrine system consist
glands that secrete hormones
what is the role for insulin/ control
controls the blood sugar level
