The document summarizes the main sensory and effector systems in the human body. It describes the key receptors for sight (eyes), hearing (ears), touch (skin), smell (nose), taste (tongue) and balance (inner ear). It also outlines the main components and functions of the skeletal system (bones and joints) and muscular system (striated, smooth and cardiac muscle).
Brain And Five Senses
The document summarizes the main parts and functions of the human brain and sensory systems. It discusses that the brain is responsible for overseeing the body's daily operations and interpreting sensory information. It describes the three main parts of the brain - the cerebrum, cerebellum, and brain stem - and their functions in voluntary control, coordination, and vital processes. It also outlines the five basic senses - sight, hearing, smell, taste, and touch - and their associated sensory receptors and organs that detect stimuli and transmit messages to the brain.
5 Senses - How our senses work
The document summarizes how each of the 5 human senses (smell, taste, hearing, sight, touch) works. Each sense consists of specialized sensory organs and cells that detect stimuli and transmit signals to the brain. For smell, odor molecules bind to receptors in the nose. For taste, receptors on the tongue detect sweet, salty, bitter, sour, and umami flavors. Hearing involves sound waves vibrating the eardrum and bones to stimulate hair cells in the cochlea. Sight relies on light stimulating photoreceptor cells in the retina to form images. Touch is mediated by mechanoreceptors, thermoreceptors and other receptors in the skin that detect pressure, temperature and pain.
Nervous system
This PowerPoint presentation provides an overview of the nervous system. It explains that the nervous system is made up of the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system. The central nervous system is protected by the skull and vertebral column. The brain is divided into the forebrain, midbrain, and hindbrain. Neurons and glial cells are the basic cells of the nervous system that transmit signals and provide support. The senses gather information from the environment and send it to the brain via sensory neurons.

UNIT 2 Sensitivity
The document summarizes key aspects of the nervous system and senses. It discusses how the nervous system is made up of the central nervous system (brain and spinal cord) and peripheral nervous system. It captures information from the five senses through sense organs like the eyes, ears, nose, tongue and skin. This sensory information is sent to the brain via sensory neurons. The brain then interprets the information and sends signals to the rest of the body using motor neurons to coordinate responses. The nervous system controls everything we do through reflex actions and voluntary movements.
The senses by Keka, María and Carlota
This document discusses the five senses - sight, smell, taste, hearing and touch. It describes the organs associated with each sense and the basic process of how each sense works. For sight, it explains how light enters the eye and is focused on the retina. For smell, it notes receptors in the nose. It outlines the three parts of the ear for hearing and the process from vibrations to nerve impulses. Taste buds on the tongue are mentioned for taste. Touch is associated with the layers of skin.
Nervous system class 5
The document summarizes the main components and functions of the human nervous system. It describes the brain as the control center made up of the cerebrum, cerebellum, and brain stem. The spinal cord connects the brain to nerves throughout the body and is responsible for involuntary movements. There are sensory nerves that carry signals to the brain and motor nerves that carry signals from the brain. The five senses - sight, hearing, smell, taste, and touch - allow humans to perceive their environment through specialized sense organs like the eyes, ears, nose, tongue, and skin.
Sensitivity and Coordination by José Carlos
The document discusses the human sensory system. It describes how stimuli are detected by receptors, which send signals to the brain and spinal cord to produce responses. The main senses are sight detected by the eyes, smell by the nose, hearing by the ears, touch by the skin, and taste by the tongue. The nervous system coordinates responses through the central nervous system and peripheral nerves.
Unit 2 sensitivity and coordination ana and devorah s
The document discusses the human body's sensory and coordination systems. It describes the different stimuli the body can receive, both internal and external. It explains that the body has receptors to detect these stimuli, and that the responses can be muscular or glandular. It then outlines the five senses - sight, smell, hearing, touch, and taste - and the organs associated with each. The document goes on to discuss the nervous system, including neurons, and voluntary vs involuntary movements. It concludes by covering the skeletal system, joints, and main muscle groups in the body.
Sensitivity and coordination

It then details the five main senses - sight, hearing, touch, smell, and taste - and the specific organs associated with each. Finally, it provides an overview of the central and peripheral nervous systems, including their main components and functions.
Sensory organs
This document summarizes the main sensory organs in the body - vision, hearing, taste, smell, and touch. It describes the anatomy and physiology of the eye, ear, taste buds, olfactory system, and receptors for touch. The eye contains the retina with rods and cones for vision. The ear is divided into external, middle, and inner sections for hearing and balance. Taste buds contain gustatory cells that detect the five basic tastes. The olfactory region contains sensory cells that detect smells. Various receptors throughout the body sense touch, pain, temperature, and proprioception.
The nervous system (1)
The nervous system controls all activities of the body and is made up of the central and peripheral nervous systems. The central nervous system consists of the brain and spinal cord and controls thought, movement, and organ functions. The peripheral nervous system consists of nerves and sensory organs like eyes, ears, and skin that allow the body to receive external stimuli and react automatically through reflexes.
Unit 2 interaction and the body
The document summarizes the five senses - sight, hearing, smell, taste, and touch - and describes how each sense works and the organs involved. It then discusses the central nervous system, including the brain, cerebellum, brain stem, and spinal cord. Finally, it briefly outlines the peripheral nervous system, skeleton, joints, and muscles. The key points are that the five senses detect stimuli and send signals to the brain for processing, and that the central and peripheral nervous systems work together to receive sensory information and control the body's responses.
The human body and interaction
The document discusses the four main body systems involved in nutrition: the digestive system, respiratory system, circulatory system, and excretory system. It provides details on the organs that make up each system and their functions. The digestive system breaks down food, the respiratory system facilitates gas exchange, the circulatory system transports blood, and the excretory system eliminates waste. It also discusses the nervous system and sensory system, explaining how stimuli are received and transmitted to elicit responses.
Sensory organ
The sensory organs detect stimuli from the environment and transmit this information to the brain. The main sensory organs are the eyes, ears, nose, tongue and skin. The eyes detect light, ears detect sound, nose detects smell, tongue detects taste and skin detects touch, pressure, temperature and pain. Within each sensory organ are specialized receptor cells that detect specific stimuli like light, sound, chemicals etc. The stimuli are converted to electrical signals that travel along sensory nerves to the brain which interprets these signals as the different senses.
Sensitivity and Coordination by Sacha
The document summarizes the key human body systems including:
1) The sensory organs (eyes, ears, nose, tongue, skin) and how they receive stimuli from the environment and transmit messages to the brain.
2) The nervous system, made up of the central nervous system (brain and spinal cord) and peripheral nervous system, which interprets sensory messages and coordinates responses.
3) The skeletal and muscular systems, with bones providing structure, joints allowing movement, and muscles enabling movement when signaled by the nervous system.

The human nervous system and sense organ
The document discusses the human nervous system and sense organs. It provides details on the following:
1. The human nervous system has three main functions - receiving sensory input, integration in the central nervous system, and generating motor output in response to stimuli.
2. There are three main types of neurons - sensory neurons that receive information, interneurons that relay messages, and motor neurons that conduct signals to muscles and glands.
3. The main senses discussed are taste via taste buds on the tongue, smell via olfactory receptors in the nose, vision via light stimulating photoreceptors in the retina, and hearing via sound waves causing vibrations that stimulate hair cells in the cochlea.
CHAPTER 1_F3.pptx
The human nervous system has two main parts - the central nervous system comprising the brain and spinal cord, and the peripheral nervous system comprising nerves that connect to sensory organs and muscles. The brain controls voluntary actions that we are aware of, while involuntary actions are controlled automatically. Humans detect stimuli through five sensory organs - eyes, ears, nose, tongue and skin. The eye detects light and allows sight, while the ear detects sound to allow hearing. The nose contains olfactory receptors that detect smells, and the tongue contains taste buds to detect the five basic tastes. The skin contains various receptors that detect touch, pressure, heat, cold and pain.
Chap3.sensation,perceptionandconsciousness
This document provides an overview of sensation, perception, and the human senses. It defines sensation as the process of receiving sensory data from the environment, while perception involves interpreting and making sense of sensory stimuli. The main human senses - vision, hearing, touch, smell, and taste - are described in terms of their basic mechanisms and receptors. Key concepts in perception such as gestalt laws of organization, perceptual constancy, and depth perception are also summarized. The document concludes with a short reflection question about the relationship between sensation and perception.

Unit 2 nutrition david
We eat food to obtain nutrients and vitamins that our bodies need, and our digestive system extracts these substances. In addition to digestion, respiration or breathing is also part of nutrition by providing oxygen. The circulatory system is essential for nutrition as it transports the nutrients we eat and oxygen we breathe to our organs, bones, brain, and muscles. Our blood contains three types of cells that each perform specific functions. Vitamins are essential nutrients our bodies need. Junk food contains high levels of sugar and fat, and if consumed in excess can accumulate in our bodies, causing weight gain and potential illness.
Unit 1 interaction alvaro s
The nervous system has three main parts: the brain, spinal cord, and nerves. The brain receives information and sends messages to the body via the spinal cord and nerves.

Unit3 nutrition monica s
Nutrients provide cells with energy and four body systems work together to carry out nutrition: the digestive system breaks down food and absorbs nutrients, the respiratory system inhales oxygen and exhales carbon dioxide for cellular respiration, the excretory system filters waste from the blood and removes it from the body through sweat and urination, and the circulatory system transports blood to circulate nutrients and oxygen to cells and remove waste.
Unit 5 energy deborah and ana s
Energy can exist in multiple forms including mechanical, light, sound, thermal, electrical, chemical, and nuclear. It can be renewable sources like water, wind, sun, biomass, or waves and tides, or non-renewable sources like fuels or uranium and plutonium. Our bodies transform the chemical energy from food into mechanical energy for movement. Electricity is a form of energy that can be easily transported through power lines and transformed into other types of energy like light. Static electricity occurs when an object accumulates an electrical charge, which can be neutral, positive, or negative. Electrical current is the movement of electrical charges through a conducting material. Producing and using electricity can cause problems to the environment like
