Q

Why aren’t there “respiratory tissues” or “digestive tissues”

A

Those systems and the organs within them are made of combinations of different tissues

Function: flexible, elastic support

18
Q

Fibrocartilage

A

Type: Connective
Matrix: parallel bundles of collagen

Location: between vertebrae
Function: absorb shocks, resist forces

19
Q

Hyaline Cartilage

A

Type: Connective
Cell Type: chondrocytes inside lacunae
Matrix: Clear and glassy, no visible fibers
Location: joints, trachea, ribcage, fetus

20
Q

Compact (Cortical) Bone

A

Type: Connective
Matrix: calcified porous appaearance
Cell type: osteocytes inside lcunae
Location: generally the outer surface
Function: support and protection

21
Q

Spongy (Cancellous) Bone

A

Type: Connective
Matrix: Calcified, porous
Cells: osteocytes in lacunae
Location: inner layer of bones
Function: lightweight support

22
Q

Blood

A

Type: Connective
Matrix: fluid called blood plasma
Cells: erythroctyes (red) and leukocytes (white)
Location: heart and blood
Function: transport gasses, nutrients, waste. Defense and clotting

23
Q

Nervous Tissue

A

Function: specialized for rapid transportation
Location: Brain, spinal cord, nerves
Cell types: neurons to detect stimuli and transmit information and glials to provide protection, support, and “housekeeping”

24
Q

Muscle Tissue

A

Function: contract and exert forces on other tissues
Types: skeletal, cardiac, and smooth

25
Q

What is similar about nervous and muscular tissue?

A

Both can be electrically excited
