Nervous System

• What serves as the main processing center for the entire nervous system?

  Central Nervous System
• Nervous System connect all of the body parts and transmits signals from one part to another.
• It is a system of cells, tissues, and organs that regulates body's responses to stimuli.

  Nervous System
• Central Nervous System composed of?

  Brain and spinal cord
• It connects the central nervous system to organs and limbs.

  Peripheral Nervous System
• It organize and distribute information to the body.

  Brain
• Brain has 3 main parts:

  Cerebrum, Cerebellum and Brain Stem
• Large and upper part of the brain that controls activity and thoughts (Interpreting, reasoning, and emotion)


  Cerebrum
• It is located under the cerebrum and controls posture, balance, and coordination.


  Cerebellum
• It connects the brain to the spinal cord and controls automatic functions (Breathing, digestion and heart rate).


  Brain Stem
• It serves as channel for signals between brain and the rest of the body.

  Spinal Cord
• It control simple musculoskeletal reflexes without input from the brain.

  Spinal Cord
• This system is associated with the voluntary control of body movements.


  Somatic Nervous System
• Somatic Nervous System has 2 main parts:

  Spinal Nerves and Cranial Nerves
• It is a nerve that carry motor and sensory signals between spinal cord and the body.


  Spinal Nerve
• It is a nerve fibers that carry information into and out of the brain stem.

  Cranial Nerves
• This system is associated with the involuntary control of body movements.

  Autonomic Nervous System
• Autonomic Nervous System has two subdivisions:

  Sympathetic and Parasympathetic
• This is activated when the body is in stress (increased heart rate and breating and sweating).

  Sympathetic
• It maintains body functions and restores the body to normal/relaxed mode.

  Parasympathetic
• Nerve Cells are also called?

  Neurons
• A neuron has a cell body containing?

  Nucleus
• It carries impulses towards the cell body.

  Dendrites
• It carries impluses away from the cell body.

  Axons
• Sensory also known as afferent. From senses to brain.
• Motor also known as Efferent. From Brain to muscles.
• The body system that controls and coordinates all body activities through electrical impulses/message between brain, spinal cord and nerves

  Nervous System
• Specialized cells that carry messages throughout the nervous system

  Neurons
• It is the basic functioning unit of the nervous system

  Neurons
• It triggers ovulation.

  LH
• It turned rupture follicle become corpus luteum

  LH
• What does corpus luteum secretes?

  Estrogen and Progesterone
• Lining of the uterus

  Endometrium
• Menstrual cycle begins when a girl reaches her puberty.
