Animal Tissues

Epithelial Tissue

Common Misconceptions

Watch Out! Animal tissues are specialized for movement and control:

Misconception 1: Fat is just stored energy and isn't a real tissue. Correction: Fat (Adipose tissue) is highly active connective tissue! It insulates the body, cushions organs, and even produces important hormones.

Location: Covers the body surface, lines internal organs and cavities.
Function: Protection, secretion, absorption, and filtration.

Connective Tissue

Bone:
- Location: Forms the skeleton of the body.
- Function: Provides support, protection, and helps in movement.
Cartilage:
- Location: Found in the nose, ear, trachea, and at the ends of bones.
- Function: Provides support and flexibility, and reduces friction at joints.
Blood:
- Location: Circulates throughout the body within blood vessels.
- Function: Transports oxygen, nutrients, hormones, and waste products.
Ligament:
- Location: Connects bones to bones at joints.
- Function: Provides stability to joints.
Tendon:
- Location: Connects muscles to bones.
- Function: Transmits force from muscles to bones, enabling movement.

Ligament vs. Tendon A simple way to remember: Ligaments connect Bone to Bone (LBB), while Tendons connect Muscle to Bone (TMB).

Muscular Tissue

Striated (Voluntary or Skeletal Muscle):
- Location: Attached to bones.
- Function: Responsible for voluntary movements of the body.
Unstriated (Involuntary/Smooth Muscle):
- Location: Found in the walls of internal organs like the stomach, intestines, and blood vessels.
- Function: Responsible for involuntary movements, such as digestion and blood flow.
Cardiac (Specialized Muscle):
- Location: Found only in the heart.
- Function: Responsible for the rhythmic contractions of the heart, pumping blood throughout the body.

Nerve Tissue

Parts of Neuron:
- Cell Body (Soma): Contains the nucleus and other organelles.
- Dendron (Dendrite): Short, branched extensions that receive nerve impulses from other neurons.
- Axon: A long, slender projection that transmits nerve impulses away from the cell body to other neurons or effector cells.
