The Cell Tissues under the Microscope
i. The tissue displayed is Cardiac Muscle. This tissues actions are involuntary. Its
ii. The tissue depicted is the Smooth Muscle. Its features are:
It appears non striated
Nucleus is visible
Cells are shaped like spindles (Interactive Physiology, 2014
Its action is involuntary like the cardiac Muscle. Both of these are controlled
by neurons (part of the autonomic division of the NS) and by hormones
released by the endocrine glands. (Tortora and Derrickson, 2013)
iii. The tissue depicted is the skeletal Muscle. Cylindrical and single with clear
striation. Two major intracellular (Sarcomere) features
The centre of the sarcomere is where the proteins that hold thick filaments
together are. (M line inside the H zone) (Uniprot Subcellular Locations,
The A band, the dark sections either side of the H zone has thick and thin
filaments overlapping, causing the dark colour (Tortora and Derrickson,
The cells in the Nervous System are made up mainly of: Neurons and Neuroglia
i. The image is a transverse section of the spinal cord, from the Central Nervous
System, (Histology OLM, 2014) Grey (eg. Neuronal soma, dendrites,
unmyelinated axons) and White Matter (myelinated axons) are the two types of
ii. Motor Neuron, Cellular Features:
Dendrite: has many receptor sites for binding chemicals messengers from
other cells.( Tortora and Derrickson, 2013)
Soma (Cell Body): Signals from Dendrites are joined and passed on.
Axon: sends nerve impulses to other neurons/muscle fibres/gland cells.
(Tortora and Derrickson, 2013)
iii. Satellite cells
Surround the cell bodies of neurons in the PNS ganglia.
Structural support (Tortora and Derrickson, 2013)
Regulation of the exchange of materials between interstitial fluid and
neuronal cell bodies. (Slomianka, 2014)
