The brain is located inside the skull and is made up of neurons that communicate via electrical and chemical signals. It is split into two hemispheres and connected to the spinal cord via the brain stem. The brain controls the body's functions and houses thoughts, memories, feelings and emotions. It receives sensory input and sends motor commands via different types of neurons. Major parts include the cerebrum, cerebellum and brain stem, each with distinct roles in voluntary movement, balance, involuntary functions and sleep regulation.

The spinal cord extends from the brainstem down the back and acts as a link between the body and brain, coordinating simple reflexes. It contains gray matter in the center and white matter on the outside.
THE HUMAN BRAIN by Nadia Abdulallah
The human brain is organized into three interconnected layers - the central core, limbic system, and cerebral cortex - that work together to regulate basic life processes and higher cognitive functions. The central core controls breathing, pulse, movement, and processing sensory information. It contains five main regions: the thalamus, pons, cerebellum, reticular formation, and medulla. The limbic system, found only in mammals, mediates emotions, memory, and motivated behaviors through regions like the hippocampus, amygdala, and hypothalamus. The cerebral cortex is divided into left and right hemispheres that direct higher cognitive functions through four lobes - frontal, occipital, parietal, and temporal.

The document summarizes the structure and function of the nervous system. It describes that the nervous system is comprised of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, which act as the control center. The PNS includes nerves that connect the CNS to other parts of the body. Neurons are the basic working units that transmit signals through the nervous system. Communication occurs at synapses between neurons. The brain and spinal cord work together with the peripheral nerves to coordinate sensory input, integration of information, and motor output to control bodily functions.
The nervous system
The brain is the control tower of our body All our activities are controlled by our brain, It is located inside the bony skull of our head, which protects it from injuries. (The brain works continuously throughout day and night/t stores, retrieves and processes the information it gathers, just like computer. It also controls the working of different organs of our body.

Peter is a student at the Health Care and Paramedic Science school studying radiology and imaging technology from 2024-2027. The document provides an overview of the nervous system including its main components and functions. It describes the central nervous system consisting of the brain and spinal cord which process sensory information and coordinate bodily functions. The peripheral nervous system includes nerves throughout the body which transmit signals between the central nervous system and other parts of the body. Common disorders that can affect the nervous system are also listed such as Alzheimer's disease, cancer, cerebral palsy and epilepsy.
Nervous system
The nervous system has two main parts - the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, and acts as the main control center. The brain controls all body functions and processes sensory information. The spinal cord relays messages between the brain and body and coordinates reflexes. The PNS connects the CNS to the rest of the body using cranial and spinal nerves. It links the CNS to sensory receptors and muscles throughout the body.

The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system. The central nervous system processes information from the senses and controls and coordinates the body's activities, while the peripheral nervous system connects the central nervous system to the limbs and organs. Key components include neurons, which transmit signals; the brain, which controls the body's responses; and the spinal cord, which connects the brain to the rest of the body. The nervous system allows for voluntary and involuntary responses through reflex arcs that transmit signals from sensors to effectors.
The Nervous System
The document outlines the main organs and components of the nervous system, including the brain, spinal cord, and nerves. It describes the four main sections of the brain - the cerebrum, cerebellum, diencephalon, and brain stem - and their functions. It also discusses the central nervous system, peripheral nervous system, autonomic nervous system, and somatic nervous system.
Human nervous system for allied health students.ppt
The document discusses the structure and function of the nervous system. It describes the central nervous system as consisting of the brain and spinal cord which act as the body's control center. The peripheral nervous system is made up of nerves connecting the central nervous system to the rest of the body. Within the central nervous system, neurons transmit electrical signals through the body to coordinate its activities. The three main sections of the brain are the cerebrum, cerebellum and brainstem, each with distinct roles in movement, coordination, memory and other cognitive functions.
Nervous System-class 6.pdf
The nervous system is made up of the central nervous system (brain and spinal cord) and peripheral nervous system (nerves). The central nervous system acts as the body's control center and coordinates activities. Impulses travel through neurons to reach the brain. The peripheral nervous system connects the central nervous system to the rest of the body. Together they allow the body to rapidly respond to stimuli.
The brain is divided into the forebrain, midbrain, and hindbrain. The forebrain includes the cerebrum and controls higher functions. The midbrain connects the forebrain to the hindbrain. The hindbrain assists in regulating automatic functions and sensory information relay. Within the brain, structures such as the cerebellum,
THE-NERVOUS-SYSTEM.pdf
The document discusses the nervous system, which is made up of the central nervous system (brain and spinal cord) and peripheral nervous system. The central nervous system receives sensory information and controls responses through the brain and spinal cord. It is divided into the forebrain, midbrain, and hindbrain. The peripheral nervous system connects the central nervous system to the rest of the body through nerves and is divided into the somatic and autonomic systems. Common nervous system diseases include Alzheimer's disease, which causes memory loss and cognitive decline, and epilepsy, which involves seizures.

The document discusses the structure and function of the nervous system. It describes how the central nervous system, made up of the brain and spinal cord, coordinates the body's activities through the neurons. The peripheral nervous system connects to and relays messages from the central nervous system through sensory neurons, motor neurons, and interneurons. The three main sections of the brain - the cerebrum, cerebellum, and brainstem - each have distinct roles in controlling voluntary movement, balance, and involuntary functions. Major nervous system diseases and their prevalence and economic costs are also listed.
L9. Nervous System.ppt
The document discusses the structure and function of the nervous system. It describes how the nervous system is composed of neurons and neuroglia cells. Neurons transmit electrochemical signals and have a cell body, dendrites, and axons. There are three types of neurons - afferent, efferent, and interneurons. Neuroglia cells insulate and support neurons. The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system. The central nervous system processes information and the peripheral nervous system connects to sense organs and effectors.
Nervous System.pptx
The nervous system of vertebrates (including humans) is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The (CNS) is the major division, and consists of the brain and the spinal cord. The spinal canal contains the spinal cord, while the cranial cavity contains the brain.
Nervous system
The nervous system coordinates voluntary and involuntary actions through the central nervous system (CNS) and peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The brain, which is the most complex organ, contains structures like the cerebrum, cerebellum, and brain stem that control functions like movement, balance, vision, and basic life processes. The cerebrum contains lobes that control functions like memory, speech, and emotion. The spinal cord extends from the brain and contains regions that nerves connect to throughout the body.
Central Nervous System.pptx
The central nervous system comprises the brain and spinal cord. The brain controls bodily functions through awareness, movement, sensations, thoughts, and memory. It receives sensory input and provides motor output. The spinal cord carries messages between the brain and body and acts as a center for basic reflexes.

Weighing of the_heart (1)
The ancient Egyptians believed that after death, one's heart would be weighed on a scale against a feather. If the heart was heavy due to sinful deeds, the god Ammut, who was feared for being the devourer, would appear and eat the person's heart. However, if the heart was light due to good deeds in life, the person would pass judgment and enter the heavenly afterlife. This weighing of the heart ceremony determined one's fate in the Egyptian afterlife.
Scribes of ancient egypt
Scribes in ancient Egypt had prestigious jobs that involved years of training. They learned to write using hieroglyphics and the faster hieratic script, and would practice drawing symbols like lions and ducks. Papyrus, a plant that grew along the Nile, was used to make paper-like sheets for scribes to write on. It was processed by peeling layers and pressing the strips together. The Rosetta Stone, discovered in 1799, helped crack the hieroglyphic code because it included the same text in hieroglyphics, demotic script, and Greek.
Age of pharaohs
The document discusses several famous pharaohs and aspects of ancient Egyptian culture related to pharaoh burials. It describes how Tutankhamun became pharaoh at age 9 and how Ramesses II ruled for 67 years, building many monuments. It also discusses the Great Sphinx carved from limestone at Giza, mummification practices for pharaohs including King Tut's three coffins, small model servants and animals buried with pharaohs, and the Great Pyramid built for Khufu, which took around 20 years to complete. Later, pharaohs were buried in tombs in the Valley of the Kings.
Technology and exploration ppt
Early European explorers were able to venture further due to improvements in navigation instruments and ship design. The Portuguese and Spanish built larger, more maneuverable ships like the caravel, which had triangular sails and could sail against the wind. This enabled explorers to explore coastlines and map new areas, pushing the boundaries of European voyages. Key motivations for exploration included gaining wealth ("gold"), increasing national prestige ("glory"), and spreading Christianity ("god").
Animal structures powerpoint

Editor's Notes
- Not actually pink, actually a dull grey color Larger brains doesn’t necissarily mean more intelligent, depends on what part of the brain is larger
- 100 billion neurons in brain Left hemisphere orientated: emphasis on reason and logic Right hemisphere orientated: emphasis on creativity and imagination
- Spinal cord must be protected, protected by Cerebrospinal Fluid (CSF) CSF also protects the brain and brainstem Injuries to back may damage the spinal cord, and cause paralysis, make sure kids keep back safe
- Most of this will be extra, most information will be in notes Use own discretion on whether these lessons should be taught
- Split into five major lobes that control thought and memory, sight, sound, smell, and touch and movement
- Also controls spatial awareness, how we can know where things are without looking, such as bringing a spoon to one’s mouth without looking at the spoon
- Also called medulla Made up of three parts, midbrain, pons, and medulla oblongata
