1.2- Tissues

Question 1

What are the 4 Body Tissues?

Answer 1

Epithelial, Connective, Muscle, Nervous

Question 2

Epithelial

Answer 2

• forms the linings, coverings, and glandular tissue of the body
• protects underlying structures
• act as barriers, passage and excretion of substances
• Consists of layers of cells (one kind of cells inside & a different kind outside)
• Cells are packed tightly together to form continuous sheets

Skin, intestines, lungs

Question 3

Connective

Answer 3

• Protects, supports, and binds together other body tissues

adipose tissue (fat), cartilage, bone, blood, and lymph

Question 4

Muscle

Answer 4

Specialized to contract and cause movement and generate heat.

skeletal smooth and cardiac

Question 5

Cardiac Muscle

Answer 5

an involuntary striated muscle tissue found only in the heart and is responsible for the ability of the heart to pump blood.

heart

Question 6

Smooth Muscle

Answer 6

involuntary muscle involuntary movements like regulation of blood flow through vital organs and movement of materials along digestive and urinary passageways.

stomach, intestines, bladder and uterus

Question 7

Skeletal Muscle

Answer 7

• muscle that connects bone and skin
• help hold the skeleton together
• give the body shape
• help with everyday movements (Voluntary Muscle)

shoulder muscles, hamstring muscles and abdominal muscles

Question 8

Nervous

Answer 8

• Composed of neurons that receive and send electrical signals in the body
• Respond to stimuli and transmits impulses and together with supporting cells make up the brain, spinal cord, and nerves.

Brain, Spinal Cord

Question 9

How do forensic anthropologists use bone to determine sex

Answer 9

• Female-
  Skull: round eye sockets, v-shaped mandible, smoother frontal bone
  Pelvis: rounded pelvis, wider pubic arch
• Male
  Skull: square eye sockets, u-shaped mandible, pronounced frontal bone, heart shaped pelvis, angled-in coccyx

Question 10

How do forensic anthropologists use bone to determine race

Answer 10

Determined best by skull
* European
More “surprised” eye sockets, forehead aligns with nose and chin in a straight line
* Africain
More square eye sockets, forehead more pronounced, mandible more pronounced
* Asian
More rectangular eye sockets, nose is more vertical, chin is receding

Question 11

How do forensic anthropologists use bone to determine age

Answer 11

• Determined by Humerus or Femur or Tibia
• Check for fused bones

Question 12

How do forensic anthropologists use bone to determine age height

Answer 12

Determined best by Femur
* Length

Question 13

Formula to estimate height using **Femur

Answer 13

Male: ( 2.32 x MLF ) + 65.53 +- 3.94

Female: ( 2.32 x MLF ) + 54.10 +- 3.72

MLF = length of femur (USING CM)

Question 14

Formula to estimate height using **Humerus

Answer 14

Male: (2.97 x MLH ) + 73.5 +- 3.94
Female: (3.14 x MLH) + 65 +- 3.72

MLH= Humerus Length (USING CM)

Question 15

Formula to estimate height using **Radius

Answer 15

Male: (3.7 x MLR) + 80.5 +- 3.94
Female: (3.9 x MLR) + 73.41 +- 3.72

MLR = Radius Length (USING CM)

Question 16
