Cells & Tissue
•Clinical Context: The first responders to acute bacterial infection and tissue necrosis. They form the primary cellular component of pus.
Nervous System
The cerebellar cortex is highly organized into three distinct layers, containing five main types of neurons.
Organs
The spleen is structurally divided into two distinct functional regions based on its appearance on fresh tissue cuts: the White Pulp and the Red Pulp.
Muscles
In skeletal muscle, these proteins are broadly divided into thick filaments and thin filaments. Highly rapid, ionotropic receptors that cause direct cell depolarization upon binding.
Bone
Bone develops directly from sheets of mesenchymal (embryonic) connective tissue without any pre-existing cartilage.
Hormones
Exocrine glands can be classified either by how they secrete their products (merocrine, apocrine, holocrine) or by the nature of the secretion itself (serous, mucous).
