The Human Machine

Part 3:

Muscular Tissues

slide2

Recognize and explain that human beings, like other organisms have complex body systems of cells,tissues, and organs that interact to support an organisms growth and survival.

VSC Content Standard:

-Describe and explain that the complex set of systems found in multicellular organisms are made up of different kinds of tissues and organs which are, in turn, composed of differentiated cells-Select several body systems and explain the role of cells, tissues, and organs in the systems selected that effectively carry out a vital function for the organism, such as:Obtaining food and providing energy, Defense, Reproduction, Waste Removal, Breathing

objectives
Objectives:

Students Will:

  • Compare and contrast the three types of muscle tissue.

Homework:

  • Vocab.
lesson question
Lesson Question:

Compare a human skeletal and muscular systems to those of a bird. How does the bone structure differ? Are there any similarities? Be sure to give specific examples based on our class investigations.

Look at the pictures and consider the following:

  • What type of tissue are these structures made of?
  • Do they have different functions?
  • Which organ systems are they a part of?
  • Which part of the brain sends messages to each structure?
  • Do you think that the cells making up these structures would be different?

Calf

Heart

Check your answers:

  • The calf and heart are both made of muscle tissue.
  • The calf muscle supports your body in your lower leg and your hart pumps blood through your body.
  • The cerebrum would send a message to your calf muscle for movement (voluntary) and your brainstem would control your heartbeat (involuntary).
  • Since the jobs are different, then they would be made up of specialized cells that are slightly different.

explore how are muscles different
Explore…How are muscles different?
  • We know that muscles move your body but are there different kinds of muscles? Use the website below and your text (pp.51-53) to complete the graphic organizer:

1. What are the three types of muscle?

http://training.seer.cancer.gov/module_anatomy/unit4_3_muscle_types.html

exploring muscle types
Exploring Muscle Types

1. The main function of muscle tissue is to create movement

2. Muscles contract, or shorten, to create this movement

3. Muscles only pull or squeeze! They cannot push.

4. Three Different Types of muscle are found in the body.

skeletal muscle
Skeletal Muscle

Image taken from:

http://medic.med.uth.tmc.edu/edprog/histolog/muscle/hist-05.htm

skeletal muscle1
Skeletal Muscle

1. Attached to the bones by tendons

2. Pulls on the bone to move the joint

3. Skeletal muscles work in pairs – one works while the other relaxes. This allows the muscle to “reset” after each pull

4. Called striated muscle because of stripes or lines that appear on the muscle tissue

smooth muscle
Smooth Muscle

Image taken from:

http://medic.med.uth.tmc.edu/edprog/histolog/muscle/hist-05.htm

smooth muscle1
Smooth Muscle

1. Found in internal organs like the digestive organs (stomach) and in blood vessels.

2. Smooth muscle works involuntarily, or without thought

3. Has no striations – it’s smooth!

cardiac muscle
Cardiac Muscle

Image taken from:

http://medic.med.uth.tmc.edu/edprog/histolog/muscle/hist-05.htm

cardiac muscle1
Cardiac Muscle

1. Found in the heart

2. Looks like skeletal muscle but acts like smooth muscle

3. Involuntary – your heart beats on its own without you thinking about it!

4. Considered the “Strongest” muscle because it works all the time without a major rest

Evaluate Part 2
  • Use the knowledge you have gained from the labs and class activities to explain how the muscular system and skeletal system work together to move your bones. Be sure to HIGHLIGHT the following terms in your response:
  • bones, muscles, tendons, contract, pairs

Evaluate Part 2
  • If an athlete has injured the tissue that connects the tibia to the femur, what type of connective tissue has been injured?
  • If the same athlete has injured the tissue that connects the biceps to the humerus, what type of connective tissue has been injured?
