<u>Bone tissue</u>
You are observing a tissue under the microscope and notice dark concentric circles of matrix and osteocytes in lacunae. You identify this tissue as <u>bone tissue.</u>
<u></u>
<h3>What does bone tissue look like?</h3>
- Osteons or haversian systems are tightly packed together to form compact bone.
- The osteon is made up of concentric rings (lamellae) of matrix surrounding a central canal known as the osteonic (haversian) canal.
- The bone cells (osteocytes), which are situated between the rings of matrix, are found in regions known as lacunae.
<h3>Which 4 tissues are present in bones?</h3>
- Osteoblasts, osteocytes, osteoclasts, and osteogenic cells are the four types of bone cells that make up bone tissues.
<h3>How does bone tissue develop?</h3>
- The recruitment and growth of bone progenitor cells from neighboring tissues is the first step in the development of bone tissue.
- Next come differentiation, matrix production, and mineralization.

The antebrachial region is the forearm.
The antebrachial region is a term used in anatomy to refer to the inner forearm. The forearm refers to the region of the arm which connects the elbow and the wrist.
This region consists of two bones i.e. the ulna (medially) as well as the radius (on the lateral side).
The elbow joint is created by the connection between the trochlea of the humerus and the trochlear notch of the ulna, including the connection between the capitulum of the humerus and the head of the radius.
The medial cutaneous nerve of the forearm, also termed as the medial antebrachial cutaneous nerve, is an offshoot of the medial cord of the brachial plexus.

Answer: A) Non shared environmental influences
Explanation: Non shared environment influences are any aspects of the environment and any influences that can be different for different children within the same family. In this case , Jack was encouraged to run because he is a boy thereby enabling him to be able to run up the hill much faster than Jill despite the fact that they are both children in the same family.
