13. structure and function of skeletal muscles
Skeletal muscles are the muscles that are attached to bones and are responsible for movement of the body. They are composed of muscle fibers, connective tissue, blood vessels, and nerves.
Structure:
Each skeletal muscle is composed of bundles of muscle fibers, which are made up of myofibrils that contain contractile proteins called actin and myosin. These myofibrils are organized into repeating units called sarcomeres, which give the muscle its striated appearance. The muscle fibers are surrounded by connective tissue called endomysium, which also contains blood vessels and nerves. Bundles of muscle fibers are grouped together into fascicles, which are surrounded by another layer of connective tissue called perimysium. Multiple fascicles make up the entire muscle, which is surrounded by a layer of connective tissue called epimysium.
Function:
The main function of skeletal muscles is to generate force to produce movement of the body. When the muscle fibers contract, the actin and myosin filaments slide past each other, causing the sarcomeres to shorten and the muscle to contract. This contraction generates force that is transmitted through tendons to the bones, causing movement of the body. Skeletal muscles also help to maintain posture and stability of the body, and they play a role in regulating body temperature. Additionally, they can store and release energy through the breakdown of glycogen, a carbohydrate stored in muscle tissue.

Overall, zoology has a broad scope that includes many different areas of study and applications, all centered around the biology of animals.
17 Structure of Skeletal Muscle
Skeletal muscle is composed of long, cylindrical cells called muscle fibers. The muscle fiber is surrounded by a plasma membrane called the sarcolemma, and the cytoplasm of the muscle fiber is called the sarcoplasm. Myofibrils are the contractile elements of the muscle, and they are composed of sarcomeres, which are the contractile units of the muscle. Sarcomeres are composed of thin actin filaments and thick myosin filaments, and they are responsible for muscle contraction. T-tubules and the sarcoplasmic reticulum play important roles in muscle contraction by allowing electrical impulses to penetrate deep into the muscle fiber and releasing calcium ions that are necessary for contraction. Finally, motor neurons control the contraction of skeletal muscles by connecting to multiple muscle fibers.

Overall, Kingdom Protista is a diverse group of eukaryotic organisms with a wide range of morphological, physiological, and ecological characteristics
19. human alimentary canal
The human alimentary canal, also known as the digestive tract or gastrointestinal (GI) tract, is a long, muscular tube that extends from the mouth to the anus. It is approximately 30 feet (9 meters) long and is responsible for breaking down food, absorbing nutrients, and eliminating waste from the body.
The alimentary canal is made up of several organs, including:
Mouth: The opening at the beginning of the alimentary canal where food enters the body.
Esophagus: A muscular tube that connects the mouth to the stomach and transports food down to the stomach using a series of muscular contractions called peristalsis.
Stomach: A muscular sac that mixes and grinds food with gastric juices to begin the process of digestion.
Small intestine: A long, narrow tube where most of the nutrients from food are absorbed into the bloodstream.
Large intestine: A wider tube that absorbs water and electrolytes from digested food, and forms solid waste (feces) for elimination from the body.
Rectum: The final section of the large intestine where feces are stored before elimination.
Anus: The opening at the end of the alimentary canal where feces are eliminated from the body.
The alimentary canal also includes several accessory organs that aid in the digestive process, such as the salivary glands, liver, pancreas, and gallbladder.
20. structure and function of neuron
A neuron is a specialized cell in the nervous system that is responsible for transmitting information between different parts of the body. It consists of three main parts:
Cell body (soma): The main part of the neuron that contains the nucleus and other organelles needed for the normal functioning of the cell.
Dendrites: Branch-like structures that extend from the cell body and receive signals (in the form of chemical or electrical impulses) from other neurons or sensory receptors.
Axon: A long, slender projection that extends from the cell body and transmits electrical impulses (also known as action potentials) away from the cell body to other neurons or muscles
Here are some key functions of neurons:
Communication: Neurons are specialized cells that transmit information throughout the body in the form of electrical and chemical signals.
Integration: Neurons receive and integrate signals from other neurons and sensory receptors to determine an appropriate response.
Plasticity: Neurons have the ability to change and adapt their structure and function in response to changes in the environment or experience.
