We use anatomical positions to describe the body because they provide a reference point. They can be used similarly to standardization tools to describe an organism’s position. Medical practitioners cannot discuss patients’ bodies without having a general awareness of anatomical position, which is particularly important in medicine.
There is a standard anatomical position for each species of organism. In this article, we will learn more about anatomical positions and why they are so important.
What is an animal cell?
Eukaryotic cells with a membrane-bound nucleus are what animal cells are made of. A group of cells must unite to form tissues, organs, and organ systems. Animal cells come in a variety of forms and sizes, ranging from a few microns to a few centimeters. The largest known animal cell, for instance, is an ostrich egg that measures 170 mm by 130 mm. We therefore can conclude that a cell’s size is affected by the activity it performs.
Animal cells are considered multicellular organisms. They also have locomotory properties and well-organized cell organelles that carry out a variety of tasks, including the plasma membrane, centriole, peroxisome, lysosome, ribosomes, mitochondria, endoplasmic reticulum, cytoplasm, nucleus, nucleolus, nuclear envelope, and Golgi apparatus.
Given that plant and animal cells are eukaryotes, both have a few cell organelles in common. All of these organelles have very similar functions. Animal and plant cells do not look, however, exactly comparable or contain all of the same organelles since they have different functions. For instance, although animal cells do not require chloroplasts, plants do, for photosynthesis.
Animal cells are often smaller than plant cells and have irregular shapes, which is another distinction between plant and animal cells. This irregular shape results from the lack of a cell wall.
Why use a diagram for animal cells?
Overall, diagrams can assist your reader in comprehending your results and comparing them to other facts. In reality, when conveying some forms of information, particularly the dense ones, diagrams are more commonly used than text.
Pictures are easier for our brains to understand than words since our brains are evolved to digest information visually.
Therefore, an animal cell diagram is useful for a better understanding of the structure and functions of an animal, since it contains a considerable amount of complex and indispensable information.
Animal Cell Structures
An animal cell contains several parts and in this topic, you will comprehend every element of the construction of an animal cell that must be identified when projecting a diagram.
It is a thin, lipid- and protein-rich membrane covering the semipermeable cell. Its main function is to shield the cell from its surroundings. It also regulates how nutrients and other little things enter and leave the cell. Due to this, cell membranes are referred to as semi-permeable or selectively permeable membranes.
It is an organelle that holds several different suborganelles, including chromatins, nucleolus, and nucleosomes. The genetic material DNA is found in the nucleus nucleolus area. A nuclear membrane separates the nucleus from the remainder of the cell. It controls how cells divide and develop as well.
The nuclear membrane envelops the nucleus, as was already stated. It is a double-membrane structure also known as the nuclear envelope.
It is a tiny organelle that can be found close to the nucleus. Its dense center is surrounded by radiating tubules. Microtubules are created at the centrosomes.
They are membrane-enclosed, spherical organelles that contain digestive enzymes that support not only digestion but cell regeneration and excretion.
They are little organelles that are the locations of protein production and are composed of cytoplasmic granules rich in RNA. They can be seen floating around in the cell’s cytoplasm or bound to endoplasmic reticulum membranes.
Is a substance that is made up of all the cell organelles and is protected by the cell membrane that has a jelly resemblance. The substance found inside a cell’s nuclear membrane is known as nucleoplasm.
A flat, layered, sac-like organelle that manufactures, stores, transports, and packs the particles throughout the cell, located close to the nucleus. Assembles proteins into vesicles after receiving them from the endoplasmic reticulum.
It is a double-membraned organelle spherical or rod-shaped. It is a cell’s powerhouse since it’s crucial in the energy release process. Here, energy is released in the form of ATP during the process of cellular respiration.
It’s a cell’s internal organelle with a membrane that helps the cell keep its shape and store things like food, water, waste, and other things.
The passage of nucleic acids and proteins through the nuclear membrane is facilitated by these microscopic perforations in the membrane.
Types of Animal Cell
Animal cells come in many different varieties, each with a purpose-specific function. The most prevalent kinds of animal cells are as follows:
The skin cells from the tissues that shield the outside world from the body. It contains Merkel cells, Langerhans cells, Melanocytes, and Keratinocytes.
These extended tubular cells facilitate movement. It includes skeletal, cardiac, and smooth muscle cells.
These cells are in charge of transporting oxygen from the lungs to other parts of the body. It includes red blood cells, which lack a nucleus, as well as white blood cells, which help fight infections.
These neurons, also known as nerve cells, are part of the nervous system. The extensions that transmit or receive signals are called dendrites and axons. Glial cells and Schwann cells are also part of it.
These cells often referred to as adipocytes, are employed to store lipids and other types of fat.
