Human Body Systems HN Unit 1

System

A group of body organs that together perform one or more vital functions

The abdominal region of a body is located on the _____ area of the body.

Anterior

Deep

Away from the superficial body, more internal. "Organs are deep of the skin"

Dorsal

Being or located, ON , or torward the back or posterior part of the human Body. (Already identified as the most behind) not a situation, already has outcome

:

China, India, the US, Indonesia, Brazil

Sheets of tightly packed cells that line organs and body cavities

Epithelial

The pelvic girdle is part of the axial skeleton

False

The proximal bone of the hind or lower limb that is the longest and largest bone in the human body, extends from the hip to the knee

Femur

The Scapula is _____ to the vertebral column.

Lateral

Medial

Lying or extending in the middle; especially of a body part

What is the difference between qualitative and quantitative evidence? Explain how both types of measurements played a role in this activity.

The difference is qualitative evidence are descriptive and interpretive while quantitative evidence is numeric and measured. In this activity we used both types: quantitative for measuring lengths and such of bones and qualitative for describing bone structures.

Identity

The distinguishing character or personality of an individual

Smooth, Skeletal, Cardiac are types of this group

Muscle

This tissue transmits messages throughout the body.

Nervous

Superficial

Of, relating to, or located near the surface

ability to purse or move lips into a frown or smile is the action of:

Orbicularis oris

The developmental occurrences you used to determine age stopped at age 25. What are other clues a forensic anthropologist may be able to use to determine age if the bones belong to a person over age 25?

Other clues a forensic anthropologist may be able to use to determine if the bones belong to a person over age 25 is the skull's sutures. If the sagittal suture is completely fused a person could be about 30 to 40 years old. If it is slightly fusing ages around 24. If the coronal suture is completely fused, the person could be about 40.

Most valuable bones in sex determination

Pelvis and Skull

Ventral

Pertaining to the anterior or front side of the body, opposite of dorsal. Not situation, already the outcome

The forearm is _____ to the hand.

Proximal

Regional Terms

Refer to specific visible landmarks on the surface of the body

Lateral

Relating to the side

Posterior

Situated at or towards the hind part of the body. (Situation)

Distal

Situated away from the point of attachment or origin of a central point. Located away from the center of the body.

Inferior

Situated below and closer to the feet than another and especially another similar part of an upright body(Human being)

Anterior

Situated forwards the front of the body(situation) Ex: "The sternum is anterior to the heart"

Proximal

Situated next to or near the point of attachment or origin or central point

Superior

Situated toward the head and further away from the feet than another

Which bone determines ethnicity

Skull: Nose(Nasal Spine) Eye or orbital shape

The structure of Nerve tissue

Specialized, long and string like to send/receive impulses.

Anatomical Position

Standing straight and upright, facing forward, arms at the side, palms and hands facing forward.

The structure of skeletal muscle tissue

Striated and overlapping to contract in unison and with strength.

Why do you think the pelvis is often the first bone forensic anthropologists look to in determining sex from skeletal remains?

The male and female pelvis are significantly different so it is the bone that forensic anthropologists look for when trying to determine the gender of a skeleton. A female pelvis is wider than a males. This is because it has to be wide enough for a fetal head to fit through,

To analyze the long bones, the femur and the humerus, you looked at bone markings such as condyles, tuberosities and trochanters. Look back at the photographs and at the bone markings on your Manikin®. How would you describe these markings in your own words? Which features do you think separate each class of markings from the others?

The marks on the bones basically describe the age of the person. When your bones stop growing, they start to remodel themselves and this is what these lines represent. A tuberosity looks like a bump on the femur where the bone sticks out. A condyle is a rounded part at the end of the bone forming a joint. A trochanter is also a bump on the femur that sticks out to help determine age and connects to the hip bone.

The purpose of the Orbicularis Occuli

The purpose of the Orbicularis Occuli

The structure of epithelial tissue

Thin layers or form linings and coverings for secretion, protection, or absorption.

The inner and usually larger of the two bones of the leg between the knee and ankle that articulates above with the femur and below with the talus

Tibia

An integrated group of cells with a common structure and functiion

Tissue

The proximal popliteal artery has a clot in it. What area is this refering to?

Upper top portion-back of knee

Directional Terms

Used to explain where one body structure is; in relation to another

The four main types of tissue that make up the human body are

epithelial, connective, muscle, and nervous

Calcaneal

heel bone, is a large bone that forms the foundation of the rear part of the foot.

Axillary

relating to the armpit.

. The longest bone of the upper arm or forelimb extending from the shoulder to the elbow

Humerus

What parts of the Bone can you look at to determine age?

If a bone has a mark it could indicate the bone has had a break or fracture. If there is more cartilage, that typically means the person is typically younger because bones replace cartilage as you get older. The skull has specific sutures on it that fuse together the older you get. As you grow, so do your bones. The skull has specific sutures on it that fuse together the older you get. When your bones stop growing, they start to remodel themselves and this is what these lines represent.

Where are the smallest bones located?

In the ear

Clavicle, Scapular= Appendicular or Axial?

Appendicular

Animal tissue that functions mainly to bind and support other tissues, having a sparse population of cells scattered through an extracellular matrix

Connective

Red Blood Cells are an example of this group

Connective

Adipose is a type of

Connective tissue

Tendon are an example of which group?

Connective tissue

The function of muscle tissue is to

Contract and produce active movement
