Animal Tissue - Last hour quick revision (Tissue and organs)

▶Histology = Study of tissue
▶Marcello Malpighi = Founder of histology
▶Mayer = Coined the term histology
▶Bichat = Coined the term tissue, father of histology.

▶There are Four types of animal tissue. They are:

1) Epithelial tissue:-
      - Covering epithelium
      - Glandular epithelium

2) Connective tissue:-
      - Skeletal tissue 
      - Vascular tissue
      - Connective tissue proper

3) Muscular tissue:- 
      - Skeletal muscle
      - Smooth muscle
      - Cardiac muscle

4) Nervous tissue:-
      - Neuroglial cells
      - Neurons


▶Epithelial tissue are the only tissue derived from all three germ layers and are rest upon basement membrane having minimal intercellular spaces.

▶There are seven types of epithelium tissue. They are:-
    - Simple squamous epithelium
    - Simple cuboidal epithelium
    - Non ciliated simple columnar epithelium
    - Pseudostratified epithelium 
    - Keratinized stratified squamous epithelium 
    - Non-keratinized stratified squamous epithelium
    - Transitional epithelium

▶Most abundant type of tissue in human body is connective tissue.

▶Connective tissue are mesodermal in origin.

▶Blood, lymph, skeleton and muscles are derived from mesoderm.

▶Adipose tissue is modified for fat storage.

▶Mast cells are modified basophils of blood.

▶Mast cells secrate heparin, histamin and serotonin.(@H2S)

Tendon connects bone to muscle.

Ligament connects bone to bone. (@BoMTe BoBLi)

▶Hyaline cartilage is the most abundant cartilage.

▶Fibro cartilage is the strongest cartilage.

▶Osteology is the study of bone.

▶Myology is the study of muscle.

▶Periosteum is the outer covering of bone

▶Haversian system is present only in mammal's bone.

▶RBC of mammal is round, biconcave, non-nucleated.

▶RBC is formed in bone marrow.

▶RBC is destroyed in spleen (Graveyard of RBC).

▶Neutrophils is the most abundant type of WBC cell.

▶Monocyte is the largest type of WBC cell.

▶Lymphocyte is the smallest type of WBC cell.

▶Mnemonics for types of WBC Cells:- CLICK HERE.

▶Blood without RBC is called Lymph.

▶Blood plasma without fibrinogen is called serum.

▶Cardiac muscle is striated and involuntary.

▶Visceral muscle is non-striated and involuntary.

▶Skeletal muscle is striated and voluntary.

▶Cardiac muscle are immune to fatigue.

▶Total number of bone in adult human body is 206.

▶Total number of muscle in adult human body is 639.

▶ Strongest muscle of human body is masseter and is present in mouth.

▶Longest muscle of human body is sartorius which and is present in lower limb.

▶Largest muscle of human body is Gluteus maximus and is present in buttock.

▶Smallest muscle of human body is Stapedius and is attached to the smallest bone stapes in ear.

▶Nervous tissue originates from ectoderm(but microglia and meninges are from mesoderm).

▶Structural and functional unit of the nervous system is Neuron.

▶Longest cell of human body is Neuron.

▶Least power of regeneration is present in neurons due to the absence of centrioles.

▶Nissl's granules are present in neuron.

▶Constrictions present in the axon is called as Node of Ranvier.
