Sensory Receptor: Pacinian Corpuscle

Sensory Receptor: Pacinian Corpuscle

Pacinian cropsucles are located deep into the skin. They have concentric flattened layers of Schwann Cells. You can also see the nerve fiber in the center, and protruding out of the bottom of the corpuscle.

Key:
SC: Schwann Cells (in concentric layers)
NF: Nerve Fiber

Arrows point to some intercalated discs that appear as dark bands.

Cardiac Muscle is found only in the heart and has one or two centrally located nuclei. Note the striations which are also present in skeletal muscle, however, cardiac muscle is able to branch while smooth muscle cannot.

Elastic Connective Tissue

Elastic Connective Tissue

Key- L= The lamella of elastic material that is organized inn the form of sheets.

This photo shows that elastic material can occur in sheets rather than string-like fibers.
