Introduction to Movement

Introduction to Movement All living things are supported by some form of skeleton. Many plants and animals have what is known as an endoskeleton because it is inside the organism. Of course, an exoskeleton would be the opposite and be outside the organism. Earthworms and insects have the two types of skeleton respectively. The diagram…...

Support and movement in mammals

Support and movement in mammals Mammals have skeletons with two main parts- main axis (support) and limbs (appendages). The limbs are connected to the main axis by girdles. The skeletal system shown above is that of a human. For mammals however, the direction of the axial skeleton is usually horizontal. Most of the system is…...

Muscles and Movement

Muscles and Movement The three types of muscle in mammals are: 1. Cardiac- (this you learnt about earlier when we did transport in animals) 2. Smooth– also known as involuntary muscle as the individual has no control over it. 3. Striated– these muscles are attached to the bone and are also called voluntary muscles as…...

Structure and Function of Bone

Structure and Function of Bone The compact bone that is seen in the diagram below is the hardest bone. The layer of spongy bone which is beneath it helps to prevent the bone from being too heavy and has spaces in it. The bone marrow is in the centre of the bone structure. As the…...

Joints

Joints Joints are located where two bones meet each other. There are two main kinds of joints: 1. Synovial joints– example: the shoulder joint and elbow joint. This is where two bones need to move freely. Ligaments hold the bones together (they stretch when the bones move). Lubrication for the joint is provided by the…...

Locomotion in plants vs. animals

Locomotion in plants vs. animals The skeletons in plants are mainly for the purpose of support as plants do very little movement. Plants will not move their entire bodies but parts of their body may move. Growth Movements This involves movement due to stimuli such as gravity, light, water, touch and chemicals. Plants will grow…...

Characteristics of Living Organisms: Movement and Reproduction

Movement Movement is one of the characteristic features of living organisms; it is defined as the change in place or position by the entire body or by one of its parts. There are two types of movement in animals: muscular and non muscular. Muscles and bones work together in the body for movement to occur.…...
