Study Set Content:
- forms the brain, spinal cord, and nerves.
- It is responsible for coordinating and controlling many body activities.
Nervous tissue
Nervous tissue consists of neurons and support cells, termed
Glial cells
- is responsible for conducting electrical signals.
Neuron
a thin sheet or layer of tissue that covers a structure or lines a cavity
Tissue membrane
- The skin, termed the, is an external body surface membrane.
cutaneous membrane
- line cavities that open to the outside of the body, such as the digestive, respiratory, and reproductive tracts.
mucous membranes
- consist of three components: a layer of simple squamous epithelium, its basement membrane, and a delicate layer of loose connective tissue.
Serous membranes
Many, but not all, mucous membranes secrete
mucus
- line the cavities of freely movable joints.
Synovial membranes
- They are made up of only connective tissue and consist of modified connective tissue cells.
Synovial membranes
Synovial membranes produces
synovila fluid
- occurs when tissues are damaged.
Inflammation
- makes the joint very slippery, thereby reducing friction and allowing smooth movement within the joint.
synovial fluid
Inflammation produces five major symptoms:
redness, heat, swelling, pain, and disturbance of function.
Tissue repair involves substitution of dead cells
for viable cells
the new cells are the same type as those that were destroyed, and normal function is usually restored.
regenaration
a new type of tissue develops, which eventually produces a scar and causes loss of some tissue function.
replacement
Provides protection ,regulates temperature, prevents water loss, and helps produce vitamin D. Consists of skin, hair, nails, sebaceous glands, and sweat glands.
Integumentary system
It provides protection and support, allows body movements, produces blood cells, and stores minerals and adipose tissue. It consists of bones associated of bones, associated cartilages, ligaments, and joints
Skeletal system
A major regulatory system that detects sensations and control movements, physiological processes, and intellectual functions. Consists of the brain, spinal cord, nerves, and sensory receptors
Nervous system
