Dense irregular CT?
|
(no consistent pattern)

2. Multicellular glands |
|
CT has 3 components?
|
1. specialized cells

|
Cartilage growms by two mechanisms?
|
1. Interstitial growth
2. Appositional growth |
|
3. Supporting CT
|
Cartilage and Bone
|
|
Extracellular Fluid includes three major subdivisions:
|
1. Plasma
2. interstitial fluid 3. lymph |
|
1.Hyaline Cartilage
|
most common type
(except inside joint cavities) Covered by dense perichondrium Matrix contains; collagen fibers making it tough and somewhat flexable and reduce friction bt bony surfaces |
|
Hylaine Cartilage locations?
|
Location: bt tips of ribs and bones of sternum;covers bone surface at synovial joints; support larynx, trachea, and bronchi; forming parts of nasal septum
|
|
2. Elastic Cartilage
|
contains numerous elastic fibers making it very resilient and flexible. provides support but tolerates distortion without damage and returns to original shape.
(yellowish color on gross dissection |
|
Elastic Cartilage location?
|
auricle of external ear
epigiglottis auditory canal cuneiform cartilage of larynx |
|
3. Fibrocartilage
|
little ground substance and matrix made of collagen fibers interwoven making it durable and tough. Resist compression, prevents bone to bone contact, limits movement
|
|
Fibrocartilage location?
|
Pads within knee joints
Bt pubic bones of pelvis Intervertebral disc |
|
Bones (Osseous tissue)
|
Volume of ground substance very small.
2/3 of matrix consist of mixture of calcium salts (calcium phosphate)with lesser amts of calcium carbonate. The rest of matrix is dominated by collagen fibers. |
|
Perichondrium has two layers?
|
1. Outer(fibrous layer)region of dense irregular CT
2. Inner (cellular layer) |
|
Many Mucous membranes are lined by?
|
simple epithelia (forms absorption and or secreatory functions) Such as:
simple columnar epithelium of Digestive tract Stratified squamous epithelium (mouth) Transitional epithelium (urinary tract) |
|
Ventral Body Cavity
(Coelom) |
surrounds: respiratory tract,cardiovascular,digestive,urinary, & reproductive organs.
Subdivided:Thorasic and Abdominalpelvic cavities |
|
three types of serous Membranes?
|
1. pleura
2. peritoneum 3. pericardium |
|
Serous memb can be subdivided into: Viceral and Parietal
|
Parietal: lines the inner surface of the caviy
Visceral (serous): covers the outer surface of visceral organs |
|
Primary function of Serous Membrane
|
Minimize friction bt the opposing parietal and visceral surfaces
|
|
Fluid formed on the surface of a serous Memb. ?
|
Transudate
(sm amts) just enogh to prevent friction |
|
Mucous Membranes
|
lines cavities that communicate with the exterior.
Contain: areolar tissues called Lamina propia |
|
What body organs surfaces do mucous memb cover?
|
Respiratory tract
Digestive tract Reproductive tract Urinary tract (epiethelial surfaces are kept moist at all times to reduce friction and facilitate absorption and secretion) |
|
The CT framework of the body, what do the layers do?
|
layer of CT connect the organs within the dorsal and ventral cavities with the rest of the body.
|
|
The Fasciae layers provide three things?
|
1. strengh & stability
2. Maintain the relative positions of internal organs 3. provide a route for distrubution of: *blood vessels *lymphatic vessels *nerves |
|
Fascia
|
are CT layers and wrappings that support an surround organs.
|
|
Fasiae is divide into three layer?
|
1. Superficial fascia (subcutaneous layer)&(hypodermis)
2. deep fascia 3. subserous fascia |
|
What are the three types of Muscle tissue?
|
1. Skeletal muscle tissue
2. Cardiac muscle tissue 3. Smooth muscle tissue |
|
What gives the skeletal muscle its stration look
|
Actin and Myosin filaments
|
|
Another name for Skeletal muscle?
|
Striated Voluntary Muscle
|
|
Cardiac muscle cells do not rely on nervous activity to to start a contraction. They have Specialized Cardiac muscle cells called... to establish a regular reate of contraction?
|
Pacemaker cells
|
|
Another name for Cardiac Muscle?
|
Striated involuntary muscle
|
|
Where is Smooth Muscle tissue located?
|
*walls of blood vessels
*around hollow organs (urinary bladder) *layers around resp,circulatory,digestive,& reproductive tract |
|
Another name for Smooth Muscle Tissue

Nonstriated involuntary muscle
|
|
What are the longest cells in your body?
|
Neurons
|
|
Neurons
|
longest cell in the body
cannot divide under normal circumtances, very little ability to repair. |
|
A typical Neuron has 3 parts?
|
1. cell body (large nucleus & nucleolus)
2. dentrites (receive info from other neurons) 3. axon (conducts info to otheer cells) |
|
Neuroglia
|
aka Glia cell (supporting cells)
1. maintains physical structure of tissue 2. repairs tissue framework after injury 3. performs phagocytosis 4. provides nutrient to neurons |
|
The restoration of homeostasis after a tissue has been injured involves two related processes
|
1. Inflammation
2. Regeneration |
|
Inflammation
|
s&s: swelling, redness, warmth, and pain
|
|
