Locomotion and Movement is an important chapter for NEET. This chapter carries a high weightage in the NEET examination. Here in this blog, we are providing you with summary notes, Video lectures, Tips and PYQs with detailed solutions.
Locomotion and Movement
One of the most important characteristics of living beings is movement. Animals and plants move in a variety of ways. Streaming of protoplasm is a simple form of movement in unicellular organisms such as Amoeba. Many organisms exhibit movement of cilia, flagella, and tentacles. Humans can move their limbs, jaws, eyelids, tongues, and so on. Some of the movements result in a change of location or place. Locomotion refers to such voluntary movements.
Types of Movement
Amoeboid, Ciliary, and Muscular movements are the three main types of movements that cells in the human body exhibit
Amoeboid: It is similar to amoeba pseudopodia in that macrophages, leukocytes, and even cytoskeletal microfilaments exhibit ameboid movement.
Ciliary: Ciliary movement in the tracheal epithelial lining, reproductive tract, and so on.
Muscular Movement: Muscles control the majority of movement in a multicellular organism. Breathing, heart function, digestion, appendage movement, and locomotion are all performed by various muscles in our body.
Muscle
Muscle is a specialised mesodermal tissue. Muscles contribute approximately 40-50 per cent of a human adult’s body weight. They have unique characteristics such as excitability, contractility, extensibility, and elasticity.
Types of Muscles
There are three types of muscles, which are
- Cardiac Muscle: present in the heart, striated and involuntary
- Skeletal Muscles: They are closely related to the body’s skeletal components. They have a striped appearance under the microscope and are thus referred to as striated muscles.
- Visceral Muscles: They are found in the inner walls of hollow visceral organs such as the alimentary canal, reproductive tract, and so on. They have no striation and are smooth in appearance. As a result, they are known as smooth muscles.
