Tissues and its Functions

-


Combination of a group of similar or same kind of cells. They combine to work together to do a particular or specific job. For example,

a) EPITHELIA TISSUE is lining the internal organs of our body i.e. their function is to lining an organ that is these tissues covering the outside of the body organs, as well as inner suface of internal organs too. Epi-means outer.

b) MUSCLE TISSUE, two types of muscle tissues (voluntary and involuntary), voluntary muscles are controlling our arms and legs where the movement is voluntary i.e. movement is in our control. At the same time involuntary muscles is in our heart (CARDIAC MUSCLE-a specialized muscle found in the heart) and gastrointestinal system, and also other parts of the body too where the movement is involuntary i.e. not in our control.

c) CONNECTIVE TISSUE, blood, fat, cartilage, and bone are the examples of connective tissue, because they differ much from other tissues. CARTILAGE is an elastic fibrous tissue attached bones. There are two types of connective tissues a) LOOSE CONNECTIVE TISSUES b) DENSE CONNECTIVE TISSUES.

Loose connective tissues are found in the AREOLAR, ADIPOSE, AND RETICULAR AREAS.Dense connective tissues are found in the CARTILAGE, BLOOD, BONE, AND LYMPHATICS.

d) NERVE TISSUE: They conduct sensory and motor impulses from the CENTRAL NERVOUS SYSTEM to and fro all over the body.

Now you can understand what is a TISSUE and how they are spread all over the body and functioning in short... We will study them later extensively..

Abdominopelvic Quadrants and Regions - Lesson 5

-
Abdominopelvic quadrants and regions are divided into 9 regions as per the division of the abdominal and pelvic cavities to explain the regions in which internal organs are found. They are as follows: Hypochondriac, epigastric, lumbar, umbilical, inguinal, and hypogastric. Now we will see about all abdominopelvic quadrants and regions one by one now. 1. Hypochondriac regions (2): The two upper right and left regions below the cartilage (chondr/o) of the ribs that extend over the abdomen. 2. Epigastric regions (2): This is the region above the stomach. 3. Lumbar regions (2): The two right and left regions near the waist part of the body. 4. Umbilical regions (1): The region of the umbilicus or navel portion of the body. 5. Inguinal regions (2): The two lower right and left regions of the body, inguin/o means groin that is the area where the two legs join together with the trunk of the body. This region is also called iliac regions because they are near the ilium part

Body Cells and Differentiation-Lesson 1

Body cells are different types. We often may read about stem cell types. Like in a movie there are many actors to do their different roles to establish a story, in our body there are different kinds of cells to do different roles to keep the body stable and active. The cells in our body are of two types: 1. Somatic cells. Our body contains Muscle cells, Nerve cells, Skin cells, and Fat cells. These kind of cells performing mainly body related functions and so they are called Somatic cells. There are varieties of cells inside the body. Every cell is different or specially created to do their special role inside the body throughout. Fat Cell: For example in body cells a FAT CELL has in it empty and large spaces for fat storage, and a muscle is slender and long and has in it fiber material that help in relaxing and contracting, as well as a skin cell is square in shape and also flat in structure to give protection to our body and a nerve cell which is long in struct
