1.
2 groups of muscles and how they are controlled: involuntary - can't control them (automatic) like digesting food
voluntary - decide when you want to move them
2.
3 types of muscle tissues: skeletal, smooth, cardiac
3.
4 parts of bone: compact bone, bone marrow, spongy bone and outer membrane
4.
4 types of movable joints: hinge, ball - and - socket, pivot, sliding
5.
backbone: bone that makes up the center of the skeleton
6.
ball and socket joint: freely in a circle; hips and shoulders/swinging your arm in a circle
7.
bone marrow: soft connective tissue in the spaces in bone
8.
bones are?: strong, lightweight, hard and contain minerals
9.
cardiac muscle: inside your heart, involuntary, striated
10.
cartilage: type of connective tissue that is more flexible than bone
11.
cell: basic unit of structure and function in living things
12.
circulatory system: transports materials to and from body cells
13.
compact bone: has small canals with blood vessels running through
14.
connective tissue: connects and supports parts of your body, bones
15.
digestive system: takes food into the body and breaks it down
16.
do skeletal muscles react quickly and tire easily?: yes
17.
endocrine system: controls body process by means of chemicals
18.
epithelial tissue: covest he surface of your body and lines internal organs. skin on your body. digests and absorbs nutrients in food
19.
excretory system: removes waste
20.
five major functions of the skeleton: provides shape and support, enables you to move, protects your organs, produces blood cells and stores minerals until your body needs them
21.
heart beats: the repeated contractions of cardiac muscle
22.
hing joint: moves forward and backward, knees and elbows
23.
homeostatis: process by which an organism's interal environment is kept stable in spite of changes int he external environment
24.
how do bones form: as the body grows cartilage is replaced with bone, by the time the body is done growing all cartilage is replaced by bone, cartilage covers the ends of many bones in adults.
25.
immune system: protects the body from disease-causing bacteria and viruses
26.
integumentary system: protects the body from injury and disease and helps regulate body temperature
27.
joint: place in your body where two bones come together
28.
keeping bones healthy: balanced diet and excersize
29.
levels of organisms, smallest to largest: cells, tissues, organs, organ systems
30.
ligaments: strong connective tissue that holds bones and movable joints together
31.
long bones or arms and legs make?: certain blood cells
32.
musclue tissue: allows body to move, contract or shorten, muscles in your legs
33.
muscular system: works to move the body by pulling onthe skeleton
34.
nervous system: takes in information from the environment and from within the body and commands the body to respond
35.
nervous tissue: allows youto see, hear and think. carries electrical messages from brain to parts of body, brain cells
36.
nucleus: control center that directs the cell's activities and contains information that determinees the cell's form and function
37.
organ: structure made up of different kinds of tissues and does specific jobs. heart is an organ. organis have specific functions more complex than a tissue
38.
organ system: group of organs that work together to perform a major function
39.
osteoperosis: body's bones become weak and break easily
40.
outer membrane: where blood vessels and nerves enter and leave the bone
41.
outside boundary of an animal cell: cell membrane
42.
pivot joint: allows one bone to rotate around the other, your neck
43.
reproductive system: contains organs that produce sex cells
44.
respiratory system: takes oxygen into the body
45.
skeletal muscle: attached to your skeleten inside your body, voluntary and striated
46.
skeletal muscles work in pairs to move bones, describe: they can only move bones by cotnracting or shortening. as on contracts, the other relaxes to it's original length
47.
skeletal system: supports and protects the body
48.
skeleton helps body move how?: provides a framework that supports and protects many other body parts
49.
skull: bones that protect your brain
50.
skull is held together by what kind of joints?: immovable joints
51.
sliding joint: allows one bone to slide over the other; writs and ankles
52.
smooth muscle: inside many internal organs, involuntary, not striated
53.
spongy bone: strong, but lightweight because it has many small spaces within it
54.
stress: the reaction of your body to potentially, threatening, challenging or disturbing events.
55.
sweating: helps your body maintain a constant temperature throughout the day
56.
tendon: strong connectie tiess that attaches muscles to bones
57.
tissue: a group of specialized cells that perform the same function
58.
tissues of the human body: muscle, nervous, connective and epithelial
59.
two kinds of joints: immovable and moveable
60.
vertebrae: 26 small bones that make up the backbone
61.
what carries on the process that keeps organisms alive: cells
62.
what happens when a an elbow bends?: bicep muscles contract and tricep muscles relaxes and extends.
63.
when do bones cells form new bone tissue?: when you play a sport some of your bones absorb the weight force and respond by making new tissue. also new tissue is formed as you grow.
