Science 3rd quarter

• What does the Cell Body contain?

  Nucleus
• The reaction to a stimulus by a muscle or gland

  Response
• The sense organ or cells that receive stimuli from within and outside the body

  Sense receptor
• The branching filaments that conduct nerve impulses towards the cell

  Dendrites
• The structure at the end of an axon that produces neurotransmitter to transmit the nerve impulse across the synapse

  Axon terminal
• The covering of fatty material that speeds up the passage of nerve impulses

  Myelin Sheath
• Where does the neurotransmitter transmitted

  Between neurons at a synapse
• A rapid automatic response to a stimulus

  Reflex
• The connection between two adjacent neurons

  Synapse
• The chemical secreted into the gap between neurons at a synapse

  Neurotransmitter
• The long fiber that carries the nerve impulses

  Axon
• A bundle of axons.

  Nerve
• is a change in the environment that causes one to initiate an impulse

  Stimuli
• What are the three parts of a neuron

  Cell body, dendrites, axon
• It has the ability to change a stimulus into an impulse or an electric signal that travels in it

  Nerve cell or neuron
• The nerve cell is also called as

  Neuron
• also responsible for your startle reflex

  Midbrain
• Associated with heartbeat, breathing, sensations, and reflex control when a person is swallowing, vomiting, coughing, hiccupping,and sneezing

  Medulla Oblongata
• connects the parts of the brain; also helps control breathing

  Pons
• has several functions that include the coordination of muscular movements and reflexes that direct the movement of the eyes, head and neck every time we need to look at things around us.

  Midbrain
• What are the three regions of Brain Stem

  Medulla oblongata

  Midbrain

  Pons
• connects the brain and the spinal cord

  Brain stem
• helps in smooth coordination of skeletal muscle contractions, also regulates body posture and balance.

  Cerebellum
• The largest part of the brain; controls your ability to read, write, and speak; also related to your mathematical and musical skills; also deals with your memory.

  Cerebrum
• What are the major parts of the brain

  Cerebellum

  Cerebrum

  Brain stem
• Enumerate the lobes of the brain.

  Frontal Lobe

  Parietal Lobe

  Occipital Lobe

  Temporal Lobe
• controls the sense of smell and hearing; has a role in memory

  Temporal lobe
• controls the sense of sight

  Occipital lobe
• controls most of the senses such as touch and taste; also responsible for controlling pain, body temperature, and balance

  Parietal lobe
• controls some voluntary motor functions, different moods, and sense of smell

  Frontal lobe
• What are the two hemispheres of your Brain

  Left hemisphere

  Right hemisphere
• It processes most of the signals that it receives from the different parts of the body

  Brain
• Is an important part of the Nervous System

  Brain
• It functions whenever the body is at rest and recovery. During these periods, the body conserves and restores energy.

  Parasympathetic nervous system
• What are the two that are contained by Autonomic Nervous System

  Sympathetic nervous system and parasympathetic nervous system
• It works involuntarily and it functions independently and is not consciously controlled. It regulates the smooth and cardiac muscles as well as other glands.

  Autonomic nervous system
• Where is the cranial nerve located

  Brain
• Is responsible for your quick reaction.

  Nervous system
• serves as the processing area of the nervous system

  Central nervous system(CNS)
• serves as the connection from the brain to the rest of the body.

  Spinal cord
