Tissues Flashcards
study of tissues
Histology
A _________ is a group of cells that work together to carry out one or several functions in organisms such as plants and animals.
tissue (from latin texere = weave)
Nervous Tissue
Brain
Spinal Cord
Nerves
Epithelial tissue
Lining of GI tract organs and other hollow organs
Skin surface (epidermis)
Muscle tissue
Cardiac muscle
Smooth muscle
Skeletal muscle
Connective tissue
Fat and other soft padding tissue
Bone
Tendon
tissues that cover the external and internal surfaces of the body. Their major functions include protecting and underlying structures, permitting or denying the passage of substances, and secreting or absorbing substances.
Epithelial Tissues
Cell layering of Epithelial tissue
Simple
Stratified
Pseudostratified
Transitional
Cell shape of Epithelial tissue
Squamous
Cuboidal
Columnar
tissues characterized by large amount of extracellular materials that support and bind together the parts of the body. They also function to fill up spaces between or within organs.
Connective Tissues
is a type of tissue present in the ‘group metazoans’, for the body movement or locomotion. ‘Metazoans’ are the multicellular organisms belongs to the kingdom Animalia, whose cells differentiates to form tissues and organ. Muscular tissue provides mobility to the body organs of the organism.
Muscle tissue
Muscle tissues are of three types namely _____,_____,_____ which are structurally and functionally different from each other.
striated/skeletal, unstriated/smooth, and cardiac muscle
are attached to the bones by tendons and their contraction and relation are mediated by the central nervous system.
Striated or skeletal tissues
are present on the wall of hollow internal organs and their activity is controlled by the autonomous nervous system.
Smooth muscles or unstriated
is located within the myocardium layer of the heart and its activity is controlled by the electrical impulses from the sinoatrial node or cardiac conduction system. The shape of skeletal, smooth and cardiac muscular tissues are characteristically different, as they possess cylindrical, spindle-shaped and branched fibre, respectively.
Cardiac muscle
_____ , also called _____ , is the main tissue component of the nervous system. The nervous system regulates and controls body functions and activity.
Nervous tissue, neural tissue
Two extensions of neurons:
Dendrites
Axons
consists of scattered cells with intercellular spaces occupied by delicate fibers.
Fibrous (Category of Tissues)
- not a typical connective tissue, because it has very little extracellular matrix fibers with collagen, and is elastic.
Adipose
- also referred to as soft bone. It has a firm yet elastic matrix (chondrin) secreted by small groups of round cartilage cells (chondrocytes) embedded within it.
Cartilage
made up a mineralized matrix composed largely a ______ . It supports and protects other tissues and organs of the body and provides attachment for the muscles and tendons essential for locomotion.
Bone or Osseus, tricalcium carbonate
Bone or Osseus
Long bone
Short bone
Irregular bone
Flat bone
Category of tissues
Fibrous
Adipose
Cartilage
Bone or Osseus
consists of a liquid matrix enabling it to transport and distribute materials within the body e.g., gases, hormones, digested food).
Blood (Cellular components of blood)
