MT30-Histology Art AB 3 years, 11 months agoGiant Multipolar Neuron (Nerve Tissue)-
The cell bodies of multipolar neurons have three or more processes linked to them. The axon is a process that conveys electrochemical impulses (action potentials) between cells. Dendrites are the remaining processes.
-
Multipolar neurons’ receptive zone is made up of the cell body and dendrites. The most frequent form of neuron is the multipolar neuron. They are found in the autonomic ganglia and the central nervous system (brain and spinal cord).
-
Dendrites in multipolar neurons allow them to accept impulses from many neurons. Dendrites send messages across the neuron by an electrical signal that passes down the axon. Motor neurons feature the most common sort of nerve cell body plan: they are multipolar, having one axon and multiple dendrites.

MT30-Histology Art AB 3 years, 11 months agoCardiac Muscle Tissue (Muscle Tissue)-
In vertebrates, cardiac muscle, commonly known as myocardium, is one of three major muscle groups found only in the heart. Cardiac muscle, like skeletal muscle, has contractile units known as sarcomeres; however, this feature also separates it from smooth muscle, the third muscle type.
-
Cardiac muscle is distinguished from skeletal muscle by its regular contractions and lack of voluntary control. The sinoatrial node of the heart, which functions as the heart’s pacemaker, controls the rhythmic contraction of cardiac muscle.
-
The heart is primarily made up of cardiac muscle cells (or myocardium). The contractility of the heart, which is the foundation for its pumping function, and the rhythmicity of the contraction are two of its most notable qualities.
-
The cardiac output (the volume of blood pumped by the heart per minute) changes to fulfill the metabolic needs of peripheral tissues like skeletal muscles, kidneys, brain, skin, liver, heart, and gastrointestinal system.
-
In the heart, cardiac muscle cells form a highly branching cellular network. They are structured into layers of myocardial tissue that wrap around the chambers of the heart and are joined end to end by intercalated disks.
-
Individual cardiac muscle cells contract, producing force and shortening in these bands of muscle, resulting in a reduction in heart chamber size and blood ejection into the pulmonary and systemic veins.

MT30-Histology Art AB 3 years, 11 months agoSkeletal Muscle Tissue (Muscle Tissue)-
Skeletal muscle makes up about 40% of the body’s total mass and is the most widespread and widely distributed muscle tissue.
-
It is located in the eyes, throat, diaphragm, and anus and creates all of the skeletal muscles, such as the biceps brachii and gluteus maximus.
-
Skeletal muscle tissue cells have four characteristics: they are voluntary, striated, non-branched, and multinucleated.
-
Skeletal muscle tissue is the only muscle tissue that is controlled directly by the cerebral cortex of the brain, earning it the title of voluntary muscle.
-
Skeletal muscle tissue is responsible for all conscious body movements, including limb movement, facial expressions, eye movements, and swallowing. As a consequence of cellular metabolism, skeletal muscle contractions also produce the majority of the body’s heat.
-
Skeletal muscle cells are also distinct from other muscle tissues due to their shape. During fetal development, skeletal muscle cells are formed by the union of several smaller cells, resulting in long, straight muscle fibers with many nuclei.
-
Skeletal muscle cells display a striped, or striated, pattern of light and dark regions when examined under a microscope. The orderly organization of actin and myosin proteins within cells into structures known as myofibrils causes these stripes.
-
The skeletal muscles’ remarkable strength and capacity to pull with incredible force and push the body is due to myofibrils.

MT30-Histology Art AB 3 years, 11 months agoSmooth Muscle Tissue (Muscle Tissue)-
Smooth muscle, also known as involuntary muscle, is a type of muscle that has no cross stripes when examined under a microscope. It is made up of slender spindle-shaped cells with a single nucleus in the center.
-
Unlike striated muscle, smooth muscular tissue contracts gently and automatically. Much of the musculature of internal organs and the digestive system is made up of it.
-
Smooth muscle cells measure 3-10 m in thickness and 20-200 m in length. The cytoplasm is predominantly made up of myofilaments and is uniformly eosinophilic. During contraction, the nucleus, which is positioned in the core, takes on a cigar-like shape.
-
Caveolae are small pouch-like invaginations in the cytoplasm formed by the cell membrane, which act similarly to T-tubules in the skeletal muscle. A basal lamina anchors smooth muscle cells to the surrounding connective tissue.
-
Smooth muscle fibers are grouped together in branching bundles. These bundles, unlike skeletal muscle fibers, are not precisely parallel and organized, but rather form a complicated structure. As a result, the cells can contract significantly more forcefully than striated muscle.

The World Health Organization (WHO) also reported ischemic heart disease as the number one cause of death worldwide as of 2019. Thus, it is safe to say that heart diseases are indeed the world’s greatest killer.
