What is macroscopic view? microscopic and macroscopic view point in thermodynamics.
Microscopic anatomy (micro; small) is a branch of anatomy that relies on the use of microscopes to examine the smallest structures of the body; tissues, cells, and molecules. … This is known as histology (his-TOL-o-je; the study of tissues).
Gross (macroscopic) anatomy is the study of anatomical structures that can be seen by the naked eye, such as the external and internal bodily organs. Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.
Human macroscopic anatomy is about appearance, position and structures of organs and tissues of the body.
Gross anatomy is the study of the larger structures of the body, those visible without the aid of magnification (Figure 1a). Macro– means “large,” thus, gross anatomy is also referred to as macroscopic anatomy.
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Bone macroscopic structure allows a bone to be divided into regions based on position or morphology. This is important for a number of reasons including how growth may be affected by injury.
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope.
It’s divided into several branches, including histology, embryology, gross anatomy, zootomy, phytotomy, human anatomy, and comparative anatomy.
According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells.
Definition of macroscopic 1 : observable by the naked eye. 2 : involving large units or elements.
The macroscopic world contains the things we can see with our eyes. The microscopic world contains the building blocks of matter, the atoms and molecules. We know they are there, but we can’t see them directly. The mesoscopic world is in between the microscopic and the macroscopic world.
Macroscopic forms of energy are those that a whole system possesses with respect to a fixed external reference. In thermodynamics, the macroscopic forms of energy are potential energy and kinetic energy. Potential and kinetic energy are based on external position and velocity references, respectively.
The main difference between cytology and histology is that cytology is the study of chemistry, structure, and function of animal and plant cells, whereas histology is the study of chemical composition, microscopic structure, and function of tissue and tissue systems.
Functional Anatomy uses the basic structural knowledge provided in Human Anatomy to develop an understanding of the functional significance of the structures of the musculoskeletal system, within a movement setting (covering mechanical properties and functional characteristics).
Life processes of the human body are maintained at several levels of structural organization. These include the chemical, cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. … That is why cells are so small.
Cells are microscopic, meaning they can’t be seen with the naked eye. The reason cells can grow only to a certain size has to do with their surface area to volume ratio. … Here, surface area is the area of the outside of the cell, called the plasma membrane.
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Osteoblasts are specialized mesenchymal cells that synthesize bone matrix and coordinate the mineralization of the skeleton. These cells work in harmony with osteoclasts, which resorb bone, in a continuous cycle that occurs throughout life.
Bone is a strong, flexible and semi-rigid supporting tissue. It can withstand compression forces, and yet it can bend. Like cartilage, and other types of connective tissue, bone is made up of Cells and Extracellular matrix: Cells – which in bone are called osteoblasts and osteocytes, (osteo – bone).
24013. Anatomical terminology. The diaphysis is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
a. The arrangement or formation of the tissues, organs, or other parts of an organism. b. An organ or other part of an organism.
Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. In contrast, cytopathology examines free cells or tissue micro-fragments (as “cell blocks”).
In order to study tissues with a microscope they must be preserved (fixed) and cut into sections thin enough to be translucent. Fundamentally it consists of a chemical or physical method of killing the tissue and yet retaining characteristic peculiarities of shape and structure. …

As Hippocrates is called the Father of Medicine, Herophilus is called the Father of Anatomy. Most would argue that he was the greatest anatomist of antiquity and perhaps of all time. The only person who might challenge him in this assessment is Vesalius, who worked during the 16th century A. D.
The smallest organ in the body is the pineal gland, relative to its function. It is situated centrally in the brain, between the hemispheres in a groove. Size is about 8mm in humans.

It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1.3).
Specialties and subdivisions of physiology include cell physiology, special physiology, systemic physiology, and pathological physiology, often called simply pathology.
Macroscopic: Large enough to be seen with the naked eye, as opposed to microscopic.
macroscopic organisms (MACK-row-SKAWP-ick) Organisms big enough to be seen by the eye without the aid of a microscope.
Microscopic approach considers the behaviour of every molecule by using statistical methods. In Macroscopic approach we are concerned with the gross or average effects of many molecules’ infractions. These effects, such as pressure and temperature, can be perceived by our senses and can be measured with instruments.
The macroscopic scale is the length scale on which objects or phenomena are large enough to be visible with the naked eye, without magnifying optical instruments. It is the opposite of microscopic.
The physical properties of matter can be viewed from either the macroscopic and microscopic level. The macroscopic level includes anything seen with the naked eye and the microscopic level includes atoms and molecules, things not seen with the naked eye. Both levels describe matter.
Elements and atoms Because this operation is carried out on bulk matter, the concept of the element is also a macroscopic one. The atom , by contrast, is a microscopic concept which in modern chemistry relates the unique character of every chemical element to an actual physical particle.
From Wikipedia, the free encyclopedia. A macroscopic quantum state is a state of matter in which macroscopic properties, such as mechanical motion, thermal conductivity, electrical conductivity and viscosity, can be described only by quantum mechanics rather than merely classical mechanics.
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
Kinetic energy is the energy of motion. This can be the motion of large objects (macroscopic kinetic energy), or the movement of small atoms and molecules (microscopic kinetic energy). Macroscopic kinetic energy is “high quality” energy, while microscopic kinetic energy is more disordered and “low-quality.”
Biopsies usually involve larger pieces of tissue than a cytology test needs, and a pathologist may examine several types of cells in a tissue sample taken from a biopsy. Biopsy procedures are also generally more invasive than cytology tests and may require local or general anesthesia.
