Animal Response and movement

Which interactions occur among body systems to create a response to a stimuli?

• The integumentary system carries a message to circulatory system.

• The nervous system sends electrical signals to muscular and skeletal system.

• Endocrine system transmits chemical messages to the respiratory system.

• The muscular system sends a message to the excretory system

What is the role of a motor neuron

• To transmit information from the sensory receptors to the central nervous system

• To exchange information between other kinds of neurons

• To carry information from interneurons to muscles

• To interpret information in the form of electrical signals in the brain.

What is the sequence of signal transmission in response to a stimulus?

• Motor neuron to interneuron to sensory neuron to muscle

• Sensory neuron to interneuron to motor neuron to muscle

• Muscle to interneuron to sensory neuron to motor neuron

• Interneuron to motor neuron to muscle to sensory neuron.

What is one general way in which nervous systems differ among animal groups?

• Whether or not cephalization occurs

• Whether or not neurons are present

• Whether or not stimuli are recognized

• Whether or not signals are electrical or chemical

Which statement about the degree of cephalization shown by cnidarians, flatworms, and vertebrates is true?

• Flatworms have no cephalization.

• Cnidarians have a fair degree of cepalization.

• Vertebrates have a high degree of cephalization

• All animals show the same amount of cepalization

Which of the following animals has the most complex sensory system?

• Jellyfish

• Octopus

• Coral

• Sea Anemone

What is the general relationship between the complexity of an animal's nervous system and that of its sensory system?

• The sensory system tends to be unrelated to the nervous system.

• A more complex sensory system tends to be related to a more complex nervous system

• A more complex sensory system tends to be related to a less complex nervous system.

• A more complex sensory system tends to increase the complexity of the nervous system over time.

What body structures work together to enable movement?

• Muscles and bones

• Skin and muscles

• Bones and Blood vessels

• Blood vessels and skin

Why are the largest land animals vertebrates?

• Endoskeletons continue to grow throughout the life of an animal

• Only animals with endoskeletons are mobile

• Endoskeletons are lightweight in proportion to the bodies they support

• Endoskeltons make it possible to transport fluids throughout an animal's body.

Each of the following is a characteristic common to the skeletons of all vertebrates except:

• located inside the body

• large and dense

• lightweight in proportion to the body

• made up of cartilage and/or bone
