Question

Anatomy Tutorial: Connective, Muscle, and Neural Cells

Answer 1

\({\bf{Connective~Tissue:}}\) protects and insulates organs/ other tissues
> ground substance/matrix: homogeneous substance containing fibers and other connective tissue
> types of fibers: elastic, reticular (thin fibers, support blood vessels in muscle cells), collagen (support bones, tendons, ligaments)
> mesenchymal cells: can turn into antimicrobial cells
> fibroblasts: produces collagen + other fibers, involved in healing
> fat cells
> melanocytes: produce pigment
> plasma cells: produce antibodies
> mast cells: dilate blood vessels

Answer 2

\({\bf{Muscle~Cells:}}\) cells bound end to end in fibers, multi-nucleated
> skeletal: contains dark bands of muscle (overlapping microfilaments). voluntary.
> cardiac: (also striated). voluntary. only located in the heart.
> smooth: non-striated. involuntary. found in stomach, bladder, blood vessels.

Answer 3

\({\bf{Neural~Cells:}}\) creates and transmits nerve impulses, carrying information to and from other cells

> cell body: contains the organelles, nucleus, cytoplasm, etc.
> axon: where nerve impulses travel down to other cells
> dendrites: receive impulses from other cells



(covered this in greater detail in my biology tutorials)

Answer 4

Anyway, that's the end of my tutorial, I hope it was a helpful resource. Source material is the Princeton Review Anatomy Workbook, 4th ed.
