How many body divisions does a snail have?
A snail's body is characterized by a soft body within a hard shell. The basic divisions of its body are the head, the viscera, and the foot. The head contains the brain and mouth supports the tentacles, two of which also serve as eyestalks. The viscera (organs) are almost all within the shell. The foot that provides movement extends from the shell, but both it and the head are connected to the shell by muscles. These can draw the entire body back into the shell if needed.
What are three organs or tissues that make up the cardiovascular system?
The three organs or tissues that make up the cardiovascular system are the heart, blood vessels, and blood.
How many synapses occur in this reflex arc?
In a simple reflex arc, there are typically three neurons and two synapses. The sensory neuron carries the signal from the receptor to the central nervous system, where it synapses with the interneuron. The interneuron then synapses with the motor neuron, which carries the signal to the effector organ to produce a response.
What are the three basic components of every feedback control system?
The three basic components of every feedback control system are: the sensor (or detector) which measures the system's output, the controller which processes this information and generates a control signal, and the actuator (or final control element) which takes the control signal and adjusts the system's input to achieve the desired output.
What are three organs of the skeletal system?
Three organs of the skeletal system are bones, cartilage, and ligaments. Bones provide structural support and protection for organs, cartilage provides cushioning between bones, and ligaments connect bones to one another.
What is the visceral muscle known as?
Muscles are made up of "excitable cells" which can contract. Visceral muscle is smooth muscle--one of three types of muscles in the body. Visceral muscle is found in the body in places like the arteries, bladder, the digestive tract and many other muscles which need to contract in order to perform their job.
What is the Every mollusk has a head body and .?
Every mollusk has a head, a foot, and a visceral mass. The head typically contains sensory organs and the mouth, while the foot is a muscular structure used for locomotion. The visceral mass houses the internal organs, including the digestive, reproductive, and excretory systems. Together, these three components define the basic body plan of mollusks.
What are the Names of the three kinds of organs?
lungs, liver, kideny, heart are some of the examples of organs present in animals and human beigns.
What are the organs that make up the respiratory system?
Three examples would be; lungs,diaphragm, and bronchi.
What are the three parts of a negative feedback loop?
sensor, intergrator and effector
Are there any three organs that are the same in your body?
The lungs and kidneys are examples of organs for which there are two in the body. Generally, each organ is different and has different functions.
Three kinds if muscles tissue are?
Skeletal, cardiac, and smooth (visceral).
What are three body organs?
Three body organs are: the brain, the heart, the liver.
What are the three parts of homeostatic regulatory mechanism?
The three parts of a homeostatic regulatory mechanism are the receptor (detects changes in the internal or external environment), the control center (receives information from the receptor and initiates a response), and the effector (carries out the response to restore balance or stability).
What are three examples of sensory organs?
Eyes - responsible for vision Ears - responsible for hearing and balance Nose - responsible for smelling
What are the 3 main body regions of a fish?
The main body regions of a fish are the head, trunk, and tail. The head contains sensory organs and feeding structures, the trunk is where the main body organs are located, and the tail provides propulsion for swimming.
What are the three compounds of a homeostasis feedback mechanism?
The three major components include the sensor, the integrator, and the effector. For example: if you place your hand near a hot flame, your skin senses the heat and signals the brain which integrates the incoming info and sends a message to the muscles, the effector, to pull away from the flame.
