In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. [1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3]
Note-taking has been an important part of human history and scientific development. The Ancient Greeks developed hypomnema, personal records on important subjects.In the Renaissance and early modern period, students learned to take notes in schools, academies and universities, often producing beautiful volumes that served as reference works after they finished their studies.
There are four basic types of animal tissues: muscle tissue, nervous tissue, connective tissue, and epithelial tissue. [5] [9] All animal tissues are considered to be subtypes of these four principal tissue types (for example, blood is classified as connective tissue, since the blood cells are suspended in an extracellular matrix, the plasma).

1855 field notes with synonymy of Hypophyllum (quoted literature) with Omphalia and Agaricus (added handwritten notes) Several origins of genus name Agaricus have been proposed. It possibly originates from ancient Sarmatia Europaea , where people Agari, promontory Agarum and a river Agarus were known (all located on the northern shore of Sea of ...
Digital note-taking offers flexibility and convenience that traditional handwritten notes can’t match. With seemingly unlimited space, you’ll never run out of room to capture ideas, lists, or ...
Cell junctions are especially abundant in epithelial tissues. Combined with cell adhesion molecules and extracellular matrix , cell junctions help hold animal cells together. Cell junctions are also especially important in enabling communication between neighboring cells via specialized protein complexes called communicating (gap) junctions .
The main types are loose connective tissue, adipose tissue, fibrous connective tissue, cartilage and bone. The extracellular matrix contains proteins, the chief and most abundant of which is collagen. Collagen plays a major part in organizing and maintaining tissues. The matrix can be modified to form a skeleton to support or protect the body.
Memories can include titles of books the teacher read aloud, the class pet’s name, a field trip destination, a play conducted, a rainy day game played indoors, a math exercise or a song the ...
