Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

01.06 Bone Tissue Assignment Directions: Build a bone model using household materials (newspapers‚ cardboard‚ tape etc.). Attach a labeled picture or labeled drawing of your bone doing a typical function. Label the bone diagram. Finally‚ answer the conclusion questions with complete sentences. Note: If you are unable to build a bone model‚ you may watch this video instead. You must complete this assignment AS IF you had done what was shown in the video—so pay careful attention.

highly vascularized tissue with a unique capacity to heal and remodel without leaving a scar (Sommerfeldt‚ et.al‚ 2001). Furthermore‚ its primary function is to provide structural support of the body and has the capacity to store minerals‚ support muscle contraction resulting in motion‚ bears the load of the body and protects internal organs. The knowledge in Bone biology and its related application together with its challenges gave way to an emerging trend called the Bone Tissue Engineering. As it

In Bio 202 one way we’ve learned to examine a cell is by taking advantage of the differences within the chemical reactivity of the molecules located within (Lab Manual‚ Chp. 5).

When we’re sick we all use one thing a lot; facial tissues. We use them without even thinking about how they’re made or what was needed to make them. We just blow our noses and throw them away. You can tell how Eco foe your tissue just by what kind it is. Is it a two ply or a three ply? Is there special things in it like Vicks or not? The short life of a facial tissue starts out as a tree. Facial tissues are made from a mix of pine‚ spruce‚ fir‚ hemlock‚ larch‚ aspen and birch trees.

altogether. Within the biomedical engineering realm‚ there are multiple subspecialties that graduates have a choice from. Because multiple subspecialties coincide‚ those who decide to develop or test artificial organs‚ can be referred to as tissue engineers. Tissue engineering can be defined as the use of cells and engineering materials to

The primary xylem and primary phloem tissues are pushed inward into the] pith and outwards respectively by the continuous production of secondary tissues cut I off by the cambium ring. The primary xylem is gradually pushed inward and is found at the centre of the axis; whereas‚ the primary phloem‚ being soft in nature‚ gets completely crushed. These activities in the stelar region exert a great pressure outwardly. The cortex cells‚ the pericycle and the epidermis divide anticlinally to cope

Osmosis in Potato Tissue Experiment Background Information Osmosis can be defined as the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. The semi-permeable membrane allows small particles through it but does not allow large particles such as sodium chloride. Osmosis will continue until a state of equilibrium is reached i.e. there is no area with a higher or lower concentration than another area
