Tissues and Organs
Reflexes
A reflex is a response to a stimulus that bypasses the brain The input signal travels a short distance to the spinal cord, and the body automatically responds back
Sensory reseptors
A sensory detail is a bundle of nerve cells that interact with stimuli and send signals to the brain for processing.
Organs and organ system
An organ is a structure that contains at least two different types of tissue functioning together for a common purpose. An organ system is a group of organs that come together to function as a system.
Connective Tissue
Connective tissue serves a connecting function. It supports and binds other tissue together.
Epithelial Tissue
Epithelial tissue covers the external surface, internal cavities, and organ glands are also composed of epithelial tissue.
Information processing
In multicellular organisms, the body is composed of multiple interacting subsystems.These systems communicate with one another to function as a whole and respond to their environment.Sensory receptors respond to stimuli by sending messages to the brain for immediate behavior, or storage as memories
Muscle Tissue
Muscle tissue is used for locomotion, food movement in the gut, and heat the production. 3 types: Cardiac, Skeletal, Smooth
Information processing cont.
Nerve cells, or neurons, transmit information in the form of electrical signals. The nervous system has two parts:The central nervous system is made up of the brain and spinal cord, and serves as the main processing center for information.The peripheral nervous system connects the central nervous system to limbs and organs
Nervous Tissue
Nervous tissue is the main component of the nervous system, which includes the brain, spinal cord and branching nerves.
Types of sensory reseptor
Pain Receptors - Detect and respond to internal or external pain. Thermoreceptors - Gives animals the ability to sense heat and cold. Mechanoreceptors - The ability to sense touch, pressure,sound, and balance. Chemoreceptors - The sense of taste and smell. Photoreceptors - Sensitive to light and allow animals to see
Nervous system function
Sensory Input - Receives signals from sensory receptors. Integration - Interpret the sensory signals to form appropriate responses. Motor output: Conduct signals from the integration centers to the effector organs (muscles and glands), to carry out the body's respons.
Circulatory system
The circulatory system carries oxygen and to every cell in the body The circulatory system includes the: Heart,Veins,Arteries,Capillaries,Blood
Central Nervous System
The complex of nerve tissues that controls the activities of the body. In vertebrates it comprises the brain and spinal cord.
Digestive system
The digestive system breaks down food into usable nutrients and expels the wastes
Motor output
The motor output is a function of three inputs - sensory, cognitive, and intrinsic.
Muscular system
The muscular system consists of skeletal, smooth, and cardiac muscles. The muscular system handles the movement of the body, maintains posture, and circulates blood throughout the body.
Peripheral nervous system
The peripheral nervous system outside the brain and spinal cord.
Respiratory system
The respiratory system brings in oxygen to be carried by the red blood cells to different parts of the body.
Skeletal muscle tissue system
The skeletal system is in charge of providing support for the body. Contains joints which allow for movement. The skeletal system produces all the red blood cells for the body and protects all major organs.
Sensory stimuli
There are three main forms of stimuli that activate sensory systems in multicellular organisms. Mechanical stimuli, Vibrations, pressure, Chemical stimuli, Food chemicals, Oderants, Electromagnetic stimuli, Light,Heat.
Tissue
Tissues are groups of cells that have similar shape and function. 4 types: Nervous, Muscle, Epithelial, Connective
Inergration
an act or instance of combining into an integral whole.
