UNIT 5 COORDINATION AND NERVES



   UNIT 5    COORDINATION AND NERVES

In this unit, you will  understand the human body as a single, perfectly regulated, coordinated unit, not just a collection of unconnected systems and organ systems.



THE FUNCTION OF INTERACTION IS ESSENTIAL FOR  SURVIVAL. IT ALLOWS

 THE BODY TO PERCEIVE STIMULI OR CHANGES IN THE ENVIRONMENT AND 

RESPOND TO THEM APPROPIATELY THROUGH THE EFFECTOR ORGANS.


INTERACTION involves the following organs and systems:

  • SENSORY RECEPTORS OR SENSE ORGANS
  • THE NERVOUS SYSTEM
  • THE ENDOCRINE SYSTEM
  • THE MUSCULOSKELETAL SYSTEM









SENSORY RECEPTORS OR SENSE ORGANS








THE NERVOUS SYSTEM


You will learn about the central nervous system (the brain and spinal cord), and  how they are connected to the rest of the body’s organs by a complex network  of nerves in the peripheral nervous system.












THE NEURONS




















When a neuron is excited, a nerve impulse is generated. This impulse is transmitted along the neuron in the form of an electric current.  It always travels in one direction: it enters through the dendrites, travels to the soma and leaves through the axon.

The nerve impulse passes from one neuron to the next via connections
called   SYNAPSES


SYNAPSES











THE BRAIN





The peripheral nervous system























Autonomic Nervous System: sympathetic vs parasympathetic




The stress response and your autonomic nervous system

UNIT 5 SOLUTIONS




THE ENDOCRINE SYSTEM







  • The hypothalamus sends out releasing hormones which stimulate the secretion of pituitary hormones.

  • The pituitary hormones act on their target organs.  In many cases, these organs are endocrine glands that respond by secreting other hormones.

  • When enough of these final hormones are released, they act on the hypothalamus and pituitary gland, preventing the secretion of their respective hormones. This stpos the cascade of hormone release.
