✅Specific Cells And Tissue Types Flashcards
What are general physiology terms for specific cells and tissues?
- cell
- plasmalemma
- cytoplasm
- endoplasmic reticulum
What are terminology for muscle physiology?
Muscle fibre
- sarcolemma
- sarcoplasm
- sarcoplasmic reticulum
What are the three types of muscle?
- Smooth muscle
- Cardiac Muscle
- Skeletal Muscle
Describe smooth muscle.
-involuntary
-found in the walls of internal organs
> blood vessels
> gastrointestinal tract
-spindle-shaped cell
-single central nucleus
-lack visible striations
Describe cardiac muscles.
- involuntary
- found in the heart
- branching cell
- single central nucleus
- visible striations
Describe skeletal muscles
- 40% of body weight
- voluntary
- connected to bones for articulation/ movement
- elongated cell
- multiple peripheral nuclei
- visible striations
What is the organisation of skeletal muscle?
Muscle tissue
Connective tissues
Nerves
Blood vessels
What is the organisation of muscle?
Myofilaments Myofibril Muscle cell Fascicles Muscle
What is a typical neurone made up of?
- Dendrites
• Cell body (soma – nucleus + perikaryon)
* Axon (myelinated/non-myelinated)
• Axon terminals (telodendria)
What is bone Osseous tissue?
– Dense, supportive connective tissue
– Contains specialised cells
– Produces solid matrix of calcium salt deposits
– Around collagen fibres
What are the 4 types of cells in bone?
Osteocytes
Osteoblasts
Osteoprognitor cells
Osteoclasts
What is an osteocyte
Mature bone cell that maintains the bone matrix
What is an osteoblasts?
Immature bone cell that secretes osteoid, the organic component of bone matrix
What is an osteogenic cell?
Stem cell whose divisions produce osteoblasts
What is an osteoclast?
Multinucleate cell that secretes acids and enzymes to dissolve bone matrix
