• Write 3 differences and 3 similarities between the nervous system and the endocrine system.?

  Differences: The chemical messenger is different, in the endocrine system are the hormones, while in the nervous are the neurotransmitters, the speed in the nervous system is so much faster than in the endocrine system, the space the nervous system travels are so short, almost non-existent, while the endocrine system are long. Similarities: The target cells are in both chemicals, the effector are glands and both control and coordinate all the functions of the body.
• DISEASE & ORGAN: A mental disease: Anxiety 

  CAUSES: Accumulate stressing situations, for example the death of a family member.

  3 SYMPTOMS: 

  Feeling of panic

  Fatigue

  Hyperventilation 

  TREATMENT: cognitive behavioural therapy

  3 HEALTHY HABITS TO PREVENT DISEASE: 

  Good sleep routine 

  Have a diary

  Ask for help
• DISEASE & ORGAN:  Physical disease: multiple sclerosis.

  CAUSES:  It hasn't been discovered, it could be because of a virus or an antigen.

  3 SYMPTOMS: 

   Lost of equilibrium

   Difficult for walk 

   Muscular spasms

  TREATMENT:  The best treatment is a medication called Ocrelizumab

  3 HEALTHY HABIT TO PREVENT DISEASE: 

   Equilibrated diet

   Have an active mind

   Don’t smoke or expose yourself to excessive smoke.
• Peripheral Nervous System

  Consists of nerves and nerve ganglia; connects the central nervous system to the peripheral organs, receptors and effectors
• Parasympathetic Nervous System

  Associated with situations of rest and calm. It decreases energy expenditure, stimulates intestinal activity and is usually active at night.
• Sympathetic Nervous System

  Prepares the body for emergency situations (fight-or-flight response). It increases energy expenditure and inhibits intestinal activity.
• • THE CENTRAL NERVOUS SYSTEM is responsible for higher cognitive functions, sensory integration and coordination. It  consists of the brain and spinal cord protected by the skull and spinal column, and the meninges (three membranes of connective tissue surrounding them called: duramater, arachnoidmater and piamater)
• 1 Presynaptic terminal 2 synaptic vesicle 3 Synaptic cleft 4  neurotransmitters 5 Receptors 6 postsynaptic terminal. 

  In this process the impulse or the information is transmitted by something called synapse. The neurotransmitters pass from the axon to the dendrites.

  
• 1. Meninges, protects the cerebrum.
  2.  Frontal lobe, controls emotions and behaviour.
  3.  Hippocampus, memory.
  4.  Pituitary gland, endocrine gland.
  5.  Bulb, regulate vital functions.
  6. The cerebellum, motor coordination and balance.
  7.  Occipital lobe, secondary visual area.
  8.  Thalamus, sensory information.
  9. Corpus callosum, facilitates communication.

  
• 2 Node of Ranvier 3 Sinaptic button 4 Myelin sheath 5 Axon 6 Mitochondria 7. Dendrites 8. Nucleus 9. Soma

  
• What systems or organs are involved in coordination?

  Many body functions are controlled by the nervous system and the endocrine system. These two regulatory systems use chemical messengers to affect the function of the other organ systems and to coordinate activity at different locations in the body.
