This control center of the body - The Nervous System, This Controls, monitors and coordinates all body parts and processes  - The Nervous System, This also receives information from the environment and makes specific body parts act on that information - The Nervous System, The Nervous System is made of ___________, _____________, ________________- - brain, spinal cord and nerves, The nervous system is divided into how many parts - 2 parts, What are the 2 main parts of the Nervous System - Central Nervous System (CNS) and Peripheral Nervous System (PNS), The centra Nervous System is composed of _____________ and ______________  - brain and spinal cord, The Peripheral Nervous System (PNS) is consists of________________ - Nerves, This consists of the brain and spinal cord  - Central Nervous System, This controls all the activities of the body - Central Nervous System, Draw the Central Nervous System, This serves as the "central station" of our nervous system - Brain, It is the primary organ of the central nervous system contained in a skull - Brain, How heavy is the brain - 1.25 kg, This weighs about 1.25 kg and has a whitish pink appearance with a wrinkled surface - Brain, True or False. The human brain is made up of more than 100 billion nerve cells or neurons - True, True or False. Each neuron is connected to as many as 25,000 other neurons - True, These carry nerve impulses or electrical signals - Nerve cells or Neurons, A nerve impulse is a ___________ that moves rapidly from one end of a neuron to another - message, The brains has how many layers of protective covering? - 3 layers, What are the 3 layers of the brain - 1. outer layer (dura mater) 2. middle  layer (arachnoid) 3. The inner layer (pia mater), The brains has three layers of protective covering called _______________ - meninges, This is the skull's inner surface. It forms partitions in the skull that prevent excessive brain movement - outermost layer (dura mater), This is the layer of the brain that supplies the brain with nutrients and oxygen and cushions it from shock - middle layer (arachnoid), This is one of the layer of the brain that acts as a wall that prevents bacteria from reaching the brain - inner layer (pia mater), The brain and spinal cord are also surrounded by __________________ that cushions the brain and spinal cord against shock from jumping, walking, running and other movements - cerebrospinal fluid, True or False. The Brain is made of hemisphere - True, The brain is made up of 2 hemisphere. What are these? - Left Hemisphere and Right Hemisphere, These are connected by nerves that form a structure called corpus callosum - hemisphere, In the hemisphere, the connected by nerves that form a structure is called __________________ - corpus callosum, The right hemisphere controls the ______________ side of the body - left side, The left hemisphere controls the __________ side of the body - right side, What are the 3 Major Parts of the Brain - 1. Cerebrum 2. Cerebellum 3. Brain Stem, This part of the brain has the largest structure in the brain - cerebrum, This part of the brain is responsible for speech, memory, emotions, intelligence, reasoning, thinking, sensation - Cerebrum, This controls higher brain functions and deep grooves separate each hemisphere into 4 lobes, each with different functions - Cerebrum, What are the 4 lobes of cerebrum - 1. frontal lobe 2. Parietal Lobe 3. Occipital Lobe 4. Temporal Lobe, This is one of the lobe that responsible for executive function, decisions, personality, language, planning, movement - frontal lobe, This lobe is responsible for intelligence, reasoning, sensation, reading - Parietal lobe, This lobe is responsible for vision or sight - occipital lobe, This lobe is responsible for language, behavior, hearing, vision, emotions and memory - temporal lobe, The higher folded outer layer of the cerebrum is called ___________ - cerebral cortex, True or False. The folds, or convolutions, maximize the surface area of the brain within the limits imposed by the cranium, or skull. These folds increase the ability of the brain to store information - True, This is one of the major part that has second largest part of the brain - cerebellum, This s also known as the "little brain" - Cerebellum, This part of the brain specifically responsible for balance, posture and motor coordination - cerebellum, This part of the brain regulates the muscles as they contract and relax - cerebellum, If the cerebellum is damaged, a person maybe ____________. He or she may not be able to move his or her arms and legs - paralyzed, This is the smallest part of the brain - brain stem, This part of the brain is located at the base of the skull, just below the cerebellum - brain stem, This connects the brain and the spinal cord - brain stem, This part of the brain controls the basic life functions such as heartbeat, breathing, and digestion - brain stem, True or False. The Brain Stem has 3 parts. - True, What are the 3 parts of the Brain stem - 1. midbrain 2. pons 3. medulla oblongata , This is part of the brain stem that brings messages to the cerebrum from the sense organs - midbrain, This part of the brain stem that is responsible for eye reflexes - Midbrain, This is part of the brain stem that helps regulate sleep - Midbrain, This is part of the brain stem that is located at the upper portions of the brain stem, receives stimuli from facial areas - pons, This part of the brain stem that is in the lower portion of the brain stem - Medulla Oblongata, This is the part of the brain stem that controls the activity of the internal organs - Medulla Oblongata, This is the part of the brain stem that controls breathing, heartbeat, muscular actions of digestive organs, glandular secretions, and other subconscious activities - Medulla Oblongata,
