learning target

1. What parts does the motion system consist of?

2. How do bones, joints and muscles coordinate to complete movements?

3. What is the significance of exercise to the survival of animals?

1. Animal movement and behavior

1. What is animal behavior?

A series of activities performed by animals that are beneficial to their survival and reproduction are all animal behaviors. Such as peacocks opening their tails, geese migrating, bees collecting nectar, cheetahs preying on antelopes, etc.

2. Animal behavior often manifests itself in a variety of movements.

The movement of animals depends on certain body structures.

Animals move in many different ways.

1. Observe the skeletal specimens of rabbits and point out which bones are composed of the forelimbs and hindlimbs? Page P42

The forelimb bones are composed of humerus, radius, ulna, carpus, metacarpals and phalanges;

The hind limb bones are composed of femur, fibula, tibia, tarsus, pelvis and phalanges.

2. What parts are joints made of? What role do joints play in movement? Page P43

3. How are muscles attached to bones? Pull each group of muscles and observe the movement of the bones. Observe the connections between bones.

4. There are many joints in the human body, mainly distributed on the limbs.

Such as: shoulder joints, elbow joints, wrist joints, finger joints, etc. of the upper limbs;

Hip joints, knee joints, ankle joints, toe joints, etc. of the lower limbs.

The elbow joints and wrist joints of the upper limbs, and the knee joints and ankle joints of the lower limbs are all prone to injuries.

Make full preparations before exercising, exercise at an appropriate intensity, and wear wrist and knee pads.

Consolidation exercises

1. Which of the following groups of organs does the motor system consist of? ( )

A. Bone, bone connection, skeletal muscle

B. Bones, bone connections, skeletal muscles

C. Bones, joints, skeletal muscles

D. Bones, joints, skeletal muscles

2. The composition of the joint is ( )

A. Joint head, glenoid fossa, joint capsule

B. Articular surface, joint capsule, joint cavity

C. Articular head, glenoid fossa, articular cartilage

D. Articular surface, articular cartilage, articular cavity

3. When suffering from arthritis, the parts that may cause fluid or pus accumulation are ( )

A. Articular ligaments

B. Joint cavity

C. Joint capsule

D. Articular surface

Fill in the blanks:

1. Skeletal muscles have the characteristic of ( ) when stimulated.

2. Skeletal muscles can only ( ) bones, but not ( ) bones. Therefore, the muscles connected to bones are always coordinated by ( ) group muscles.

The skeletal muscles contract and move the bones around the joints, causing the body to move.
