What is physiology?
The processes and functions of all or part of an organism.
What is pathology / pathological?
The branch of medicine concerned with the cause, origin and nature of disease as well as changes in tissues and organs.
What are the levels of physiology?
Molecules- Organelles- Cells- Tissues- Organs- Organ systems- Organism.
What are Neural cells?
Excitable signalling cells.
What are Muscle cells?
Excitable contractile cells.
What are Epithelial cells?
.sheet-like external body covering (skin)
.internal cavity linings & renal tubules
.specialised endocrine cells (hormones
What are Connective tissue cells?
Cells found in: blood, lymph, fat,
tendons, bone.
Nerve cell definition and drawing labelled.
A type of cell that receives and sends messages from the body to the brain and back to the body.
Skeletal, Cardiac & Smooth Muscle cells?
Skeletal muscle: Produces movement, maintains posture, stabilises joints and generates heat
Smooth muscle: Found in the walls of hollow organs
Cardiac muscle: Exists only in your heart
Simple, Stratified and Glandular Epithelial Cells?
Simple: only one layer of cells.
Stratified: more than one layer of cells.
Glandular: A type of tissue that lines certain internal organs and makes and releases substances in the body, such as mucous, digestive juices, and other fluids.
Squamous epithelium: flat and sheet-like in appearance.
Cuboidal epithelium: cube-like in appearance, they have equal width, height and depth.
Columnar epithelium: column-like in appearance, meaning they are taller than they are wide.
What are the 11 body systems?
1)Reproductive 2)Respiratory 3)Circulatory 4)Digestive 5)Lymphatic 6)Skeletal 7)Muscular 8)Urinary 9)Nervous 10)Endocrine 11)Integumentary- skin.
