Study Notes
Animal Physiology (OAB 106)
- Course offered by Heliopolis University's Faculty of Organic Agriculture
- Course code: OAB 106
- First semester (Fall) 2024/2025
- Laboratory number: 1
Animal Tissues
- Presented by Prof. Dr. Islam Omara, a professor in the Animal Production Department at Cairo University,
- Additionally, a professor in Medical Statistics at Heliopolis University's Faculty of Physical Therapy, and also a professor at Heliopolis University's Faculty of Organic Agriculture.
Organization of Living Organisms
- Life begins as a single cell (zygote) after fertilization
- The zygote differentiates into various tissues
- Tissues are groups of cells with the same function
- Organs are formed by groups of tissues with similar functions
- Organ systems are a group of organs
- An organism is a group of organ systems
Level of Structural Organization
- Starting from the simplest to complex:
- Chemical level (atoms, molecules)
- Cellular level
- Tissue level (tissues pictured are smooth muscle, epithelial, and connective)
- Organ level (stomach pictured)
- System level (digestive system pictured)
- Organismal level (human pictured)
Types of Animal Tissues
- Epithelial tissue
- Connective tissue
- Muscle tissue
- Nervous tissue
Epithelial Tissues (Details)
- Made up of epithelial cells
- Cells can be arranged in single or multiple layers.
- The arrangement depends on location and function in the body
- Forms the covering of all internal and external surfaces
- Functions include:
- Protection (e.g., skin)
- Secretion (e.g., glands)
- Absorption (e.g., intestines)
- Excretion (e.g., kidneys, sweat glands)
- Filtration (e.g., respiratory tract, kidneys)
Connective Tissues (Details)
- Made up of connective cells
- Functions include:
- Binding structures together (form a framework)
- Supporting organs
- Storing fat
- Transporting substances
- Protecting against diseases
- Repairing tissue damage
- Connective tissue cells reproduce, but not as quickly as epithelial cells.
- Types illustrated included Loose Connective Tissue, Adipose Tissue and Dense Connective Tissues ( Tendon).
Muscle Tissues (Details)
- Made up of muscle cells (muscle fibers).
- Responsible for movement of the body (contraction/relaxation of contractile proteins).
- Types are classified as skeletal, cardiac, and smooth muscles.
- Skeletal: voluntary, striated, multinucleated, attached to bones
- Cardiac: involuntary, striated, branched, single nucleus, in the heart,
- Smooth: involuntary, non-striated, single nucleus, in internal organs
Nervous Tissues (Details)
- Specialized to transmit messages within the body
- Composed of neurons (nerve cells).
- Neurons have the ability to receive, transmit, and conduct impulses between body parts
- Functions include:
- To receive stimuli (inside or outside the body)
- To transmit impulses to different parts of the body.
- Neurons have different parts and types
- Nervous Tissue is made up of several parts, including dendrites, axons, and the cell body
