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
