The cell is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.

SKELETAL SYSTEM
bones, cartilage and ligaments are tightly joined to form a strong, flexible framework called skeletal system
anatomy and physiology of axial and appendicular skeletal system
Axial Skeleton: The axial skeleton includes the skull, spine, ribs and sternum.
Appendicular Skeleton:
The appendicular skeleton includes the appendages of the body, which are the shoulders, arms, hips, and legs.
A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm. The cell membrane surrounds the cell and controls the substances that go into and out of the cell. The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made.
The cellular components of blood are erythrocytes (red blood cells, or RBCs), leukocytes (white blood cells, or WBCs), and thrombocytes (platelets). By volume, the RBCs constitute about 45% of whole blood, the plasma about 54.3%, and white blood cells about 0.7%. Platelets make up less than 1%.
This is about the general physiology of sense organs for medical and paramedical professional beginners who choose pharmacy, nursing and physiotherapy to study.
Cell: The cell is the ultimate structural and functional unit of the body.
The three principal constituents of the cell are:
1. Cell membrane
2. Cytoplasm and its organelles
3. Nucleus

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
3. STRUCTURE OF A CELL
Cell forms the structural unit of all tissues and
organs of the body.
Different cells perform different functions. e.g.
nerve cell helps in conduction, cells of intestine
help in absorption and muscle cell helps in
contraction.
4. Human cell is eukaryotic. It consists of:
A. Cell Membrane
B. Cytoplasm
C. Nucleus
6. A. CELL MEMBRANE
The cytoplasm of a cell is bound on the outer aspect
by cell membrane which is also known as plasma
membrane or plasmalemma. It is 7.5 nm thick. It is
trilaminar structure consisting of phospholipid layer
sandwiched between outer and inner protein layer.
Function:
It maintains the shape of the cell.
Presents receptors on the surface of cell membrane,
which are specific for particular molecules that are
enzymes or hormones.
It helps in exocytosis and endocytosis.
7. FLUID MOSAIC MODEL(Proposed by SJ
Singer And GL Nicolson in 1972)
• According to this model, the cell membrane consists of a
phospholipid bilayer. It is made up of a polar head (hydrophilic)
and a non polar tail(hydrophobic).
• In aqueous solution phospholipids form a bilayer with the
heads directed outwards and the tails directed inwards.
• Presence of unsaturated fatty acids increases the fluidity and
the flexibility of cell membrane. Almost half of the total mass of
the cell membrane is formed of protein molecules. Some
protein molecules are present within the cell membrane and
are known as intrinsic proteins. The proteins which are held at
the outer aspect of cell membrane are known as extrinsic
proteins. Some proteins occupying the entire thickness of the
cell membrane are known as transmembrane proteins.
9. B. CYTOPLASM
• It is an aqueous substance in which cytoskeleton
is dispersed while organelles and inclusion bodies
are suspended.
• Membrane bound bodies in the cytoplasm are
known as cell organelles.
• The organelles found in a cell are endoplasmic
reticulum, golgi apparatus, peroxisome,
mitochondria, ribosome, centrosome and
lysosome.
10. 1. ENDOPLASMIC RETICULUM
Endoplasmic reticulum is a double membrane
bound interconnected network of tubules, vesicles
or flattened sacs.
a. Rough endoplasmic reticulum(rER)- is involved in
synthesis of proteins.
b. Smooth endoplasmic reticulum(sER)- is involved
in lipid synthesis.
11. 2. GOLGI APPARATUS
It is made up of anastomosing tubules of
membranes and vesicles. It helps in formation of
secretary products of carbohydrates.
12. 3. PEROXISOMES
Peroxisomes are also known as microbodies and are
membrane bound organelles. They are involved in
catabolic pathway. It results in the production of
H2O2 which is cytotoxic.
13. 4. MITOCHONDRIA
• It is a double membrane bound organelle. Although the
shape of mitochondria is variable but usually it is elongated,
cigar shaped. It localizes inside the cell at a site of
maximum energy requirement. An active cell, like liver cell
contains as many as 2000 mitochondria. Very few
mitochondria are present in an inactive cell.
• Each mitochondria consists of four compartments. Outer
membrane, inner membrane, matrix bound by outer and
inner membrane, space present between the two
membranes containing enzymes.
• The inner membrane is thrown into folds called cristae.
Aerobic respiration takes place in the matrix which is
enhanced by the cristae.

15. 5. RIBOSOMES
Complexes of RNA and proteins are ribosomes.
They lie either freely in cytoplasm of cells or are
found attached to endoplasmic reticulum or can
even be present in the mitochondria. They are the
principal organelles involved in protein synthesis.
16. 6. CENTROSOME
There is a pair of centrioles in each cell. Each
centriole has two cylindrical bodies placed at right
angles to each other.
Transverse section of the centriole shows three
tubules in single group and thus 9 groups of
tubules.
They help in synthesis of microtubules during cell
division.
17. 7. (a) LYSOSOME
They are vesicle like structures, which contain
enzymes, which include proteases,
carbohydratases, lipases, hydrolytic enzymes
etc. Lysosomal enzymes help in destruction of
bacteria.
All cells contain lysosomes except mature
erythrocytes.
18. (b) CYTOPLASMIC INCLUSIONS
Circumscribed masses present in the cytoplasm
are called as cytoplasmic inclusions. They can
be:
Lipid droplets
Glycogen granules
Pigments
Proteins
19. 8. CYTOSKELETON
It is the skeleton formed of fibres within the
cytoplasm of a cell. It maintains the shape of the
cell and helps in movement of the organelles
present in the cell.
Microfilaments
Intermediate filaments
Microtubules
20. C. NUCLEUS
It is the largest organelle of the cell. It consists of a
nuclear membrane surrounding the nucleoplasm.
Nucleolus is suspended in the nucleoplasm.
21.
22. i) Nuclear membrane- It is a double membrane bound
structure. Nuclear membrane consists of numerous
pores which regulate the exchange of metabolites
between nucleus and cytoplasm.
ii) Nucleoplasm- it is a gel like substance containing
genetic material. When the cell is at rest, the
nucleoplasm appears as a dark staining.
Nucleoplasm contains thread like material called
nuclear chromatin.
iii) Nucleolus- cells which are involved with active
protein synthesis have one or more nucleoli in their
nucleoplasm. The ribosomal RNA is transcribed in
the nucleolus.
