[What is elderberry extract?]

Elderberry extract comes from the fruit of the Sambucus nigra or Black Elder, a species found in Europe, Western Asia, North Africa, and North America. Called “the medicine chest of the common people,” Elder flowers, berries, leaves, bark, and roots have all been used for centuries in traditional folk medicines.Elder fruit contains vitamins A, B and C, flavonoids, tannins, carotenoids, and amino acids. Elderberry is believed to possess therapeutic uses as an anti-inflammatory, diuretic, and immuno-stimulant.

[Function]

1. As medicine raw material: It can promote the healing of gastrointestinal ulcers; It can be used for acute and chronic hepatitis and hepatitis evocable hepatomegaly, hepatocirrhosis; promote the healing of liver function.

2. As foodstuff colorant: Widely used in cakes, beverage, candy, ice cream etc..

3. As chemical raw material for daily use: Widely used in many kinds of green medicine toothpastes and cosmetics.

How to approach histology for Human Anatomy students. Using a key will help get you through it! Add some penguin fairy dust will help too!

There are lots of histology keys out there, but the one I showed in the video is here: https://www.penguinprof.com/uploads/8/4/3/1/8431323/histology_key.jpg

Details:

Tissue in the human body:

Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces.

A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

Two types of epithelial tissues: (1) Covering & lining epithelia and (2) Glandular Epithelium.

The number of cell layers & the shape of the cells in the top layer can classify epithelium.

Simple Epithelium – one cell layer
Stratified epithelium – two or more cell layers
Pseudostratified Columnar Epithelium – When cells of an epithelial tissue are all anchored to the basement Membrane but not all cells reach the apical surface.
Glandular Epithelium — (1) Endocrine: Release hormones directly into the blood stream and (2) Exocrine – Secrete into ducts.

Connective: contains many different cell types including: fibroblasts, macrophages, mast cells, and adipocytes. Connective Tissue Matrix is made of two materials: ground substance – proteins and polysaccharides, fiber — reticular, collagen and elastic.

Classification of Connective Tissue:
Loose Connective – fibers & many cell types in gelatinous matrix, found in skin, & surrounding blood vessels, nerves, and organs.
Dense Connective – Bundles of parallel collagen fibers& fibroblasts, found in tendons& ligaments.
Cartilage – Cartilage is made of collagen & elastin fibers embedded in a matrix glycoprotein & cells called chondrocytes, which was found in small spaces.
Cartilage has three subtypes:
Hyaline cartilage — Weakest, most abundant type, Found at end of long bones, & structures like the ear and nose,
Elastic cartilage- maintains shape, branching elastic fibers distinguish it from hyaline and
Fibrous Cartilage – Strongest type, has dense collagen & little matrix, found in pelvis, skull & vertebral discs.

Muscle: is divided into 3 categories, skeletal, cardiac and smooth.
Skeletal Muscle — voluntary, striated, striations perpendicular to the muscle fibers and it is mainly found attached to bones.
Cardiac Muscle — involuntary, striated, branched and has intercalated discs
Smooth Muscle — involuntary, nonstriated, spindle shaped and is found in blood vessels & the GI tract.

Nervous: Consists of only two cell types in the central nervous system (CNS) & peripheral nervous system (PNS):
Neurons – Cells that convert stimuli into electrical impulses to the brain, and Neuroglia — supportive cells.
Neurons — are made up of cell body, axon and dendrites. There are 3 types of neurons:
Motor Neuron — carry impulses from CNS to muscles and glands,
Interneuron – interpret input from sensory neurons and end responses to motor neurons
Sensory Neuron — receive information from environment and transmit to CNS.
Neuroglia — is made up of astrocytes, oligodendrocytes, ependymal cells and microglia in the CNS, and schwann cells and satellite cells in the PNS.
