WHO SHOULD STUDY THIS?
If you work with animals you need to understand their anatomy and physiology. This knowledge forms a foundation for everything from animal health to animal behaviour and performance.
- By understanding the parts of an animal, you have a basis upon which to understand what is normal and abnormal
- Through an understanding of the chemical and biological processes that occur in an animals body; you build that understanding even further.
- Anatomy and Physiology is a key starting point for studies in many different disciplines including: veterinary science, farming, zoological science and pet care.
You may undertake this course by itself for various reasons, such as:
- It can help you get a job, or advance your employment prospects in a job you already have.
- It can provide an opportunity to both learn a little about animals; and also discover whether you want to study at a higher level (without having to commit to a full diploma or degree up front).
- It can give you a head start for doing a more substantial qualification (eg. People who have undertaken this type of course will have a much better chance of success if they attempt a diploma or degree -because they already understand the basics, and have something to build on).
DO YOU UNDERSTAND MUSCLE TISSUE?
Types of Muscle
There are three kinds of muscle:
- smooth (or involuntary) muscle
- striated (or voluntary) muscle
- cardiac muscle
In animals smooth muscle is found in the walls of the intestines, in the urogenital system and in the blood vessels. It is called involuntary muscle because it works automatically, without any conscious effort by the person or animal. A good example is peristalsis, the muscular contractions and relaxation which move food down the oesophagus and the small and large intestines. Smooth muscle is made up of elongated, spindle-shaped cells with the nucleus placed in the middle of the cell as seen.
Striated Voluntary Muscle
These muscles are made up of bundles of long fibres. Each fibre is a muscle cell. The fibres have many nuclei that are placed near the surface of each cell. Each individual muscle cell is made up of smaller fibres called myofibrils (myo - meaning "muscle" in Greek). A sheath called the sarcolemma holds the myofibrils in a bundle and connects the muscle cell to tendons and gives elasticity. Each muscle fibre is controlled and activated by a branch from a motor neuron from the nervous system.
Under a powerful electron microscope, bands can be seen on each myofibril. This consists of very fine filaments of two proteins, actin and myosin. During the contraction of the muscle, it is believed that the actin filaments slide together so that neither the actin nor the myosin filaments actually change their lengths. The contraction of muscles is a positive action and requires energy to be carried out.
When you pick up a brick, the muscles of the arm and fingers contract as you grip the brick and the arm muscles contract as you lift the brick upwards. You can drop the brick by relaxing the arm and finger muscles. Throwing the brick requires more contraction of the muscles and a greater supply of energy. This energy is supplied as a result of a number of chemical reactions which take place inside the muscles.
One such reaction is the breakdown of a substance called Adenosine Tri-Phosphatase (or ATP). The protein filaments of myosin act as an enzyme to break down ATP to ADP (Adenosine Di-Phosphatase) and phosphoric acid. This reaction releases a great deal of energy which is used by the muscle fibres to cause contraction. As long as ATP is being broken down the muscle remains active, but when this reaction stops, the muscle becomes relaxed. Another reaction is the breakdown of glycogen into lactic acid with the production of energy.
This type of muscle is striated (or striped) and is involuntary. It differs from striated voluntary muscle in the following ways:
- the nuclei are placed in the centre of the cells
- the fibres branch out to form networks
- between the cells there are membranes called intercalated discs
- more importantly, cardiac muscle is not subject to fatigue in the way that striated voluntary muscle becomes tired and less effective
